/**
* A date-time with an offset from UTC/Greenwich in the ISO-8601 calendar system,
* such as {@code 2007-12-03T10:15:30+01:00}.
*
* {@code OffsetDateTime} is an immutable representation of a date-time with an offset.
* This class stores all date and time fields, to a precision of nanoseconds,
* as well as the offset from UTC/Greenwich. For example, the value
* "2nd October 2007 at 13:45.30.123456789 +02:00" can be stored in an {@code OffsetDateTime}.
*
* {@code OffsetDateTime}, {@link ZonedDateTime} and {@link Instant} all store an instant
* on the time-line to nanosecond precision.
* {@code Instant} is the simplest, simply representing the instant.
* {@code OffsetDateTime} adds to the instant the offset from UTC/Greenwich, which allows
* the local date-time to be obtained.
* {@code ZonedDateTime} adds full time-zone rules.
*
* It is intended that {@code ZonedDateTime} or {@code Instant} is used to model data
* in simpler applications. This class may be used when modeling date-time concepts in
* more detail, or when nl.topicus.jdbc.shaded.com.unicating to a database or in a nl.topicus.jdbc.shaded.net.ork protocol.
*
*
Specification for implementors
* This class is immutable and thread-safe.

* such as {@link Month} and {@link 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 nl.topicus.jdbc.shaded.org.threeten.bp.Month.*;
* import static nl.topicus.jdbc.shaded.org.threeten.bp.temporal.Adjusters.*;

* result = offsetDateTime.with(date);
* result = offsetDateTime.with(time);
* result = offsetDateTime.with(offset);

*

/**
* Calculates the period between this date-time and another date-time in
* terms of the specified unit.
*
* This calculates the period between two date-times in terms of a single unit.
* The start and end points are {@code this} and the specified date-time.
* The result will be negative if the end is before the start.
* For example, the period in days between two date-times can be calculated
* using {@code startDateTime.until(endDateTime, DAYS)}.
*
* The {@code Temporal} passed to this method must be an {@code OffsetDateTime}.
* If the offset differs between the two date-times, the specified
* end date-time is normalized to have the same offset as this date-time.
*
* The calculation returns a whole number, representing the number of
* nl.topicus.jdbc.shaded.com.lete units between the two date-times.
* For example, the period in months between 2012-06-15T00:00Z and 2012-08-14T23:59Z
* will only be one month as it is one minute short of two months.
*
* This method operates in association with {@link TemporalUnit#between}.
* The result of this method is a {@code long} representing the amount of
* the specified unit. By contrast, the result of {@code between} is an
* object that can be used directly in addition/subtraction:
*
* long period = start.until(end, MONTHS); // this method
* dateTime.plus(MONTHS.between(start, end)); // use in plus/minus
*
*
* The calculation is implemented in this method for {@link ChronoUnit}.
* The units {@code NANOS}, {@code MICROS}, {@code MILLIS}, {@code SECONDS},
* {@code MINUTES}, {@code HOURS} and {@code HALF_DAYS}, {@code DAYS},
* {@code WEEKS}, {@code MONTHS}, {@code YEARS}, {@code DECADES},
* {@code CENTURIES}, {@code MILLENNIA} and {@code ERAS} are supported.
* Other {@code ChronoUnit} values will throw an exception.
*
* If the unit is not a {@code ChronoUnit}, then the result of this method
* is obtained by invoking {@code TemporalUnit.between(Temporal, Temporal)}
* passing {@code this} as the first argument and the input temporal as
* the second argument.
*
* This instance is immutable and unaffected by this method call.
*
* @param endExclusive the end date-time, which is converted to an {@code OffsetDateTime}, not null

* @return the amount of the period between this date-time and the end date-time
