The toInstant() method of Temporal.ZonedDateTime instances returns a new Temporal.Instant object representing the instant of this date-time.

The toPlainDate() method of Temporal.PlainMonthDay instances returns a new Temporal.PlainDate object representing this month-day and a supplied year in the same calendar system.

The Temporal.Instant.from() static method creates a new Temporal.Instant object from another Temporal.Instant object, or an RFC 9557 string.

The hour accessor property of Temporal.PlainDateTime instances returns a integer from 0 to 23 representing the hour component of this time.

The until() method of Temporal.PlainDate instances returns a new Temporal.Duration object representing the duration from this date to another date (in a form convertible by Temporal.PlainDate.from()). The duration is positive if the other date is after this date, and negative if before.

The add() method of Temporal.PlainDateTime instances returns a new Temporal.PlainDateTime object representing this date-time moved forward by a given duration (in a form convertible by Temporal.Duration.from()).

The with() method of Temporal.ZonedDateTime instances returns a new Temporal.ZonedDateTime object representing this date-time with some fields replaced by new values. Because all Temporal objects are designed to be immutable, this method essentially functions as the setter for the date-time's fields.

The until() method of Temporal.PlainYearMonth instances returns a new Temporal.Duration object representing the duration from this year-month to another year-month (in a form convertible by Temporal.PlainYearMonth.from()). The duration is positive if the other month is after this month, and negative if before.

The Temporal.ZonedDateTime.compare() static method returns a number (-1, 0, or 1) indicating whether the first date-time comes before, is the same as, or comes after the second date-time. It is equivalent to comparing the epochNanoseconds of the two datetimes.

The with() method of Temporal.PlainMonthDay instances returns a new Temporal.PlainMonthDay object representing this month-day with some fields replaced by new values. Because all Temporal objects are designed to be immutable, this method essentially functions as the setter for the month-day's fields.
