ZoneOffsetTransition toEpochSecond() method in Java with Example

The toEpochSecond() method of java.time.zone.ZoneOffsetTransition class is used to get the epoch second for this particular zone offset transition object.

Syntax:

public long toEpochSecond()

Parameter: This method does not accept any parameter.

Return Value: This method returns the epoch second for this particular zone offset transition object.

Below are the examples to illustrate the toEpochSecond() method:
