Copyright (c) 2007-present, Stephen Colebourne & Michael Nascimento Santos.
This class is originally from the ThreeTen-Extra project. It is included here to reduce dependencies.
A date with an offset from UTC/Greenwich in the ISO-8601 calendar system, such as 2007-12-03+01:00.
OffsetDate is an immutable date-time object that represents a date, often viewed as year-month-day-offset. This object can also access other date fields such as day-of-year, day-of-week and week-of-year.
This class does not store or represent a time. For example, the value "2nd October 2007 +02:00" can be stored in an OffsetDate.
Implementation Requirements:
This class is immutable and thread-safe.
This class must be treated as a value type. Do not synchronize, rely on the identity hash code or use the distinction between equals() and ==.

Since:

v10.0.0

```
public static final OffsetDate MIN
```
    The minimum supported OffsetDate, '-999999999-01-01+18:00'. This is the minimum local date in the maximum offset (larger offsets are earlier on the time-line). This combines LocalDate.MIN and ZoneOffset.MAX. This could be used by an application as a "far past" date.
  - MAX
```
public static final OffsetDate MAX
```
    The maximum supported OffsetDate, '+999999999-12-31-18:00'. This is the maximum local date in the minimum offset (larger negative offsets are later on the time-line). This combines LocalDate.MAX and ZoneOffset.MIN. This could be used by an application as a "far future" date.

```
@Nonnull
public static OffsetDate now()
```
    Obtains the current date from the system clock in the default time-zone.
    This will query the system clock in the default time-zone to obtain the current date. The offset will be calculated from the time-zone in the clock.
    Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
    
    Returns:
    
    the current date using the system clock, not null
  - now
```
@Nonnull
public static OffsetDate now(@Nonnull
                                       ZoneId zone)
```
    Obtains the current date from the system clock in the specified time-zone.
    This will query the system clock to obtain the current date. Specifying the time-zone avoids dependence on the default time-zone. The offset will be calculated from the specified time-zone.
    Using this method will prevent the ability to use an alternate clock for testing because the clock is hard-coded.
    
    Parameters:
    
    zone - the zone ID to use, not null
    
    Returns:
    
    the current date using the system clock, not null

public static OffsetDate from(@Nonnull
                                        TemporalAccessor temporal)
```
    Obtains an instance of OffsetDate from a temporal object.
    A TemporalAccessor represents some form of date and time information. This factory converts the arbitrary temporal object to an instance of OffsetDate.
    The conversion extracts and combines LocalDate and ZoneOffset.
    This method matches the signature of the functional interface TemporalQuery allowing it to be used in queries via method reference, OffsetDate::from.
    
    Parameters:
    
    temporal - the temporal object to convert, not null
    
    Returns:
    
    the offset date, not null
    
    Throws:
    
    DateTimeException - if unable to convert to an OffsetDate
  - parse

    Validates the input.
    
    Returns:
    
    the valid object, not null
  - isSupported
```
public boolean isSupported(@Nonnull
                           TemporalField field)
```
    Checks if the specified field is supported.
    This checks if this date can be queried for the specified field. If false, then calling the range, get and with(TemporalField, long) methods will throw an exception.
    If the field is a ChronoField then the query is implemented here. The supported fields are:
    - DAY_OF_WEEK
    - ALIGNED_DAY_OF_WEEK_IN_MONTH
    - ALIGNED_DAY_OF_WEEK_IN_YEAR
    - DAY_OF_MONTH
    - DAY_OF_YEAR
    - EPOCH_DAY
    - ALIGNED_WEEK_OF_MONTH
    - ALIGNED_WEEK_OF_YEAR
    - MONTH_OF_YEAR
    - PROLEPTIC_MONTH
    - YEAR_OF_ERA
    - YEAR
    - ERA
    - OFFSET_SECONDS
    All other ChronoField instances will return false.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.isSupportedBy(TemporalAccessor) passing this as the argument. Whether the field is supported is determined by the field.
    Specified by:
    
    isSupported in interface TemporalAccessor
    
    Parameters:
    
    field - the field to check, null returns false
    
    Returns:
    
    true if the field is supported on this date, false if not
  - isSupported
```
public boolean isSupported(@Nullable
                           TemporalUnit unit)
```
    Checks if the specified unit is supported.
    This checks if the specified unit can be added to, or subtracted from, this date. If false, then calling the plus(long, TemporalUnit) and minus methods will throw an exception.
    If the unit is a ChronoUnit then the query is implemented here. The supported units are:
    - DAYS
    - WEEKS
    - MONTHS
    - YEARS
    - DECADES
    - CENTURIES
    - MILLENNIA
    - ERAS
    All other ChronoUnit instances will return false.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.isSupportedBy(Temporal) passing this as the argument. Whether the unit is supported is determined by the unit.
    Specified by:
    
    isSupported in interface Temporal
    
    Parameters:
    
    unit - the unit to check, null returns false
    
    Returns:
    
    true if the unit can be added/subtracted, false if not
  - range
```
public ValueRange range(@Nonnull
                        TemporalField field)
```
    Gets the range of valid values for the specified field.
    The range object expresses the minimum and maximum valid values for a field. This date is used to enhance the accuracy of the returned range. If it is not possible to return the range, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return appropriate range instances. All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.rangeRefinedBy(TemporalAccessor) passing this as the argument. Whether the range can be obtained is determined by the field.
    
    Specified by:
    
    range in interface TemporalAccessor
    
    Parameters:
    
    field - the field to query the range for, not null
    
    Returns:
    
    the range of valid values for the field, not null
    
    Throws:
    
    DateTimeException - if the range for the field cannot be obtained
    
    UnsupportedTemporalTypeException - if the field is not supported
  - get
```
public int get(@Nonnull
               TemporalField field)
```
    Gets the value of the specified field from this date as an int.
    This queries this date for the value for the specified field. The returned value will always be within the valid range of values for the field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date, except EPOCH_DAY and PROLEPTIC_MONTH which are too large to fit in an int and throw a DateTimeException. All other ChronoField instances will throw a DateTimeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    get in interface TemporalAccessor
    
    Parameters:
    
    field - the field to get, not null
    
    Returns:
    
    the value for the field
    
    Throws:
    
    DateTimeException - if a value for the field cannot be obtained or the value is outside the range of valid values for the field
    
    UnsupportedTemporalTypeException - if the field is not supported or the range of values exceeds an int
    
    ArithmeticException - if numeric overflow occurs
  - getLong
```
public long getLong(@Nonnull
                    TemporalField field)
```
    Gets the value of the specified field from this date as a long.
    This queries this date for the value for the specified field. If it is not possible to return the value, because the field is not supported or for some other reason, an exception is thrown.
    If the field is a ChronoField then the query is implemented here. The supported fields will return valid values based on this date. All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.getFrom(TemporalAccessor) passing this as the argument. Whether the value can be obtained, and what the value represents, is determined by the field.
    
    Specified by:
    
    getLong in interface TemporalAccessor
    
    Parameters:
    
    field - the field to get, not null
    
    Returns:
    
    the value for the field
    
    Throws:
    
    DateTimeException - if a value for the field cannot be obtained

@Nonnull
public DayOfWeek getDayOfWeek()
```
    Gets the day-of-week field, which is an enum DayOfWeek.
    This method returns the enum DayOfWeek for the day-of-week. This avoids confusion as to what int values mean. If you need access to the primitive int value then the enum provides the int value.

public OffsetDate with(@Nonnull
                                 TemporalAdjuster adjuster)
```
    Returns an adjusted copy of this date.
    This returns an OffsetDate based on this one, with the date adjusted. The adjustment takes place using the specified adjuster strategy object. Read the documentation of the adjuster to understand what adjustment will be made.
    A simple adjuster might simply set the one of the fields, such as the year field. A more complex adjuster might set the date to the last day of the month. A selection of common adjustments is provided in TemporalAdjusters. These include finding the "last day of the month" and "next Wednesday". Key date-time classes also implement the TemporalAdjuster interface, such as Month and MonthDay. The adjuster is responsible for handling special cases, such as the varying lengths of month and leap years.
    For example this code returns a date on the last day of July:
```
  import static java.time.Month.*;
  import static java.time.temporal.TemporalAdjusters.*;

  result = offsetDate.with(JULY).with(lastDayOfMonth());
 
```
    The classes LocalDate and ZoneOffset implement TemporalAdjuster, thus this method can be used to change the date or offset:
```
 result = offsetDate.with (date);
 result = offsetDate.with (offset);
 
```
    The result of this method is obtained by invoking the TemporalAdjuster.adjustInto(Temporal) method on the specified adjuster passing this as the argument.
    This instance is immutable and unaffected by this method call.
    Specified by:

    Parameters:
    
    adjuster - the adjuster to use, not null
    
    Returns:
    
    an OffsetDate based on this with the adjustment made, not null
    
    Throws:
    
    DateTimeException - if the adjustment cannot be made

                                 long newValue)
```
    Returns a copy of this date with the specified field set to a new value.
    This returns an OffsetDate based on this one, with the value for the specified field changed. This can be used to change any supported field, such as the year, month or day-of-month. If it is not possible to set the value, because the field is not supported or for some other reason, an exception is thrown.
    In some cases, changing the specified field can cause the resulting date to become invalid, such as changing the month from 31st January to February would make the day-of-month invalid. In cases like this, the field is responsible for resolving the date. Typically it will choose the previous valid date, which would be the last valid day of February in this example.
    If the field is a ChronoField then the adjustment is implemented here.
    The OFFSET_SECONDS field will return a date with the specified offset. The local date is unaltered. If the new offset value is outside the valid range then a DateTimeException will be thrown.
    The other supported fields will behave as per the matching method on LocalDate.with(TemporalField, long) LocalDate}. In this case, the offset is not part of the calculation and will be unchanged.
    All other ChronoField instances will throw an UnsupportedTemporalTypeException.
    If the field is not a ChronoField, then the result of this method is obtained by invoking TemporalField.adjustInto(Temporal, long) passing this as the argument. In this case, the field determines whether and how to adjust the instant.
    This instance is immutable and unaffected by this method call.

    Queries this date using the specified query.
    This queries this date using the specified query strategy object. The TemporalQuery object defines the logic to be used to obtain the result. Read the documentation of the query to understand what the result of this method will be.
    The result of this method is obtained by invoking the TemporalQuery.queryFrom(TemporalAccessor) method on the specified query passing this as the argument.
    
    Specified by:

  - adjustInto
```
public Temporal adjustInto(@Nonnull
                           Temporal temporal)
```
    Adjusts the specified temporal object to have the same offset and date as this object.
    This returns a temporal object of the same observable type as the input with the offset and date changed to be the same as this.
    The adjustment is equivalent to using Temporal.with(TemporalField, long) twice, passing ChronoField.OFFSET_SECONDS and ChronoField.EPOCH_DAY as the fields.
    In most cases, it is clearer to reverse the calling pattern by using Temporal.with(TemporalAdjuster):
```
 // these two lines are equivalent, but the second approach is recommended
 temporal = thisOffsetDate.adjustInto (temporal);
 temporal = temporal.with (thisOffsetDate);
 
```
    This instance is immutable and unaffected by this method call.
    Specified by:
    
    adjustInto in interface TemporalAdjuster
    
    Parameters:
    
    temporal - the target object to be adjusted, not null
    
    Returns:

                  @Nonnull
                  TemporalUnit unit)
```
    Calculates the period between this date and another date in terms of the specified unit.
    This calculates the period between two dates in terms of a single unit. The start and end points are this and the specified date. The result will be negative if the end is before the start. For example, the period in days between two dates can be calculated using startDate.until(endDate, DAYS).
    The Temporal passed to this method is converted to a OffsetDate using from(TemporalAccessor). If the offset differs between the two times, then the specified end time is normalized to have the same offset as this time.
    The calculation returns a whole number, representing the number of complete units between the two dates. For example, the period in months between 2012-06-15Z and 2012-08-14Z will only be one month as it is one day short of two months.
    There are two equivalent ways of using this method. The first is to invoke this method. The second is to use TemporalUnit.between(Temporal, Temporal):
```
 // these two lines are equivalent
 amount = start.until (end, DAYS);
 amount = DAYS.between (start, end);
 
```
    The choice should be made based on which makes the code more readable.
    The calculation is implemented in this method for ChronoUnit. The units DAYS, WEEKS, MONTHS, YEARS, DECADES, CENTURIES, MILLENNIA and ERAS are supported. Other ChronoUnit values will throw an exception.
    If the unit is not a ChronoUnit, then the result of this method is obtained by invoking TemporalUnit.between(Temporal, Temporal) passing this as the first argument and the converted input temporal as the second argument.
    This instance is immutable and unaffected by this method call.

    Returns:
    
    the amount of time between this date and the end date
    
    Throws:

  - compareTo
```
public int compareTo(@Nonnull
                     OffsetDate o)

    Values #2 and #3 represent the same instant on the time-line. When two values represent the same instant, the local date is compared to distinguish them. This step is needed to make the ordering consistent with equals().
    To compare the underlying local date of two TemporalAccessor instances, use ChronoField.EPOCH_DAY as a comparator.
    Specified by:
    
    compareTo in interface Comparable<OffsetDate>
    
    Parameters:
    
    o - the other date to compare to, not null
    
    Returns:
    
    the comparator value, negative if less, positive if greater
  - isAfter
```
public boolean isAfter(@Nonnull
                       OffsetDate other)
```
    Checks if the instant of midnight at the start of this OffsetDate is after midnight at the start of the specified date.
    This method differs from the comparison in compareTo(com.helger.commons.datetime.OffsetDate) in that it only compares the instant of the date. This is equivalent to using date1.toEpochSecond().isAfter(date2.toEpochSecond()).
    
    Parameters:
    
    other - the other date to compare to, not null
    
    Returns:
    
    true if this is after the instant of the specified date
  - isBefore
```
public boolean isBefore(@Nonnull
                        OffsetDate other)
```
    Checks if the instant of midnight at the start of this OffsetDate is before midnight at the start of the specified date.
    This method differs from the comparison in compareTo(com.helger.commons.datetime.OffsetDate) in that it only compares the instant of the date. This is equivalent to using date1.toEpochSecond().isBefore(date2.toEpochSecond()).
    
    Parameters:
    
    other - the other date to compare to, not null
    
    Returns:
    
    true if this is before the instant of the specified date
  - isEqual
```
public boolean isEqual(@Nonnull
                       OffsetDate other)
```
    Checks if the instant of midnight at the start of this OffsetDate equals midnight at the start of the specified date.
    This method differs from the comparison in compareTo(com.helger.commons.datetime.OffsetDate) and equals(java.lang.Object) in that it only compares the instant of the date. This is equivalent to using date1.toEpochSecond().equals(date2.toEpochSecond()).
    
    Parameters:
    
    other - the other date to compare to, not null
    
    Returns:
    
    true if the instant equals the instant of the specified date
  - toXMLOffsetDate
```
@Nonnull
public XMLOffsetDate toXMLOffsetDate()
```
  - equals
```
public boolean equals(Object o)
```
    Checks if this date is equal to another date.
    The comparison is based on the local-date and the offset. To compare for the same instant on the time-line, use isEqual(OffsetDate).
    Only objects of type OffsetDate are compared, other types return false. To compare the underlying local date of two TemporalAccessor instances, use ChronoField.EPOCH_DAY as a comparator.
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    o - the object to check, null returns false
    
    Returns:
    
    true if this is equal to the other date
  - hashCode
```
public int hashCode()
```
    A hash code for this date.
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a suitable hash code
  - getAsString
```
@Nonnull
 @Nonempty
 @Deprecated
public String getAsString()
```
    Deprecated.
    
    Outputs this date as a String, such as 2007-12-03+01:00.
    The output will be in the ISO-8601 format yyyy-MM-ddXXXXX.
    
    Returns:
    
    a string representation of this date, not null
  - toString
```
public String toString()
```
    Overrides:
    
    toString in class Object
