The getOffset() method of TimeZone class in Java is used to know the offset value of this TimeZone at a specific date from the UTC or the Universal Time Coordinated.
Syntax:
public int getOffset(long in_date)

Return Value: The method returns the ID of the TimeZone.
Below programs illustrate the working of getOffset() Method of TimeZone:
Example 1:
// Java code to illustrate getOffset() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone offtime_zone            = TimeZone.getTimeZone("Europe/Rome");          // Checking the offset for the systems date        System.out.println("The Offset Value is:"                           + offtime_zone                                 .getOffset(Calendar.ZONE_OFFSET));    }} |
Output:
The Offset Value is:3600000
Example 2:
// Java code to illustrate getOffset() method  import java.util.*;  public class TimeZoneDemo {    public static void main(String args[])    {          // Creating a TimeZone        TimeZone offtime_zone            = TimeZone.getTimeZone("Pacific/Pago_Pago");          // Checking the offset for the systems date        System.out.println("The Offset Value is:"                           + offtime_zone                                 .getOffset(Calendar.ZONE_OFFSET));    }} |
Output:
The Offset Value is:-39600000
