ZonedDateTime withLaterOffsetAtOverlap() method in Java with Examples

The withLaterOffsetAtOverlap() method of a ZonedDateTime class is used to return a copy of this ZonedDateTime object after changing the zone offset to the later of the two valid offsets at a local time-line overlap. The overlap happens when Daylight saving time finishes and one hour is returned to timeline. FDue to this there are two valid offsets for the local date-time and calling withLaterOffsetAtOverlap method will return a ZonedDateTime with the later of the two zones. If this method is called when it is not an overlap, this is returned. This instance is immutable and unaffected by this method call.

Syntax:

public ZonedDateTime withLaterOffsetAtOverlap()

Parameters: This method accepts no parameters.

Return value: This method returns a ZonedDateTime based on this date-time with the later offset.

Below programs illustrate the withLaterOffsetAtOverlap() method:
