ZoneOffset class represents a fixed zone offset from UTC time zone, for example, +05:30, -06:00, etc.
It is a period of time that a time zone differs from the UTC.
A ZoneOffset is not aware of the changes in zone offset because of the observed Daylight Saving Time.
The ZoneOffset class declares three constants:
UTC is the time zone offset constant for UTC.
MAX and MIN are the maximum and minimum supported zone offsets.
Z, not +00:00 or -00:00, is used as the zone offset designator for UtC time zone.
ZoneOffset class provides methods to create its instances using a combination of hour, minute, and second.
The following code demonstrates how to create instances of the ZoneOffset class.
import java.time.ZoneOffset; public class Main { public static void main(String[] args) { // Create zone offset using hour, minute, and second ZoneOffset zos1 = ZoneOffset.ofHours(-6); ZoneOffset zos2 = ZoneOffset.ofHoursMinutes(5, 30); ZoneOffset zos3 = ZoneOffset.ofHoursMinutesSeconds(8, 30, 45); System.out.println(zos1); System.out.println(zos2); System.out.println(zos3); // Create zone offset using offset ID as a string ZoneOffset zos4 = ZoneOffset.of("+05:00"); ZoneOffset zos5 = ZoneOffset.of("Z"); // Same as ZoneOffset.UTC System.out.println(zos4); System.out.println(zos5); // Print the values for zone offset constants System.out.println("ZoneOffset.UTC: " + ZoneOffset.UTC); System.out.println("ZoneOffset.MIN: " + ZoneOffset.MIN); System.out.println("ZoneOffset.MAX: " + ZoneOffset.MAX); }// ww w . j a v a 2 s . co m }
