TimeZone getOffset() Method in Java with Examples

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)

Parameters: The method accepts one parameter, in_date of long type that refers to the actual date represented in milli-seconds since 1st January 1970 at 00:00:00 GMT.

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
