The setRawOffset(int offsetMillis) method of TimeZone class in Java is used to set the base time zone offset to GMT. This offset value can be to UTC to get the local time. Syntax:
public abstract void
setRawOffset(int offsetMillis)
Parameters: The method accepts a single parameter offsetMillis of Integer type which specifies the given base time zone offset to GMT. Return Value: The method does not return any value. Below program illustrates the above-mentioned function: Program 1:Â
Java
// Program to demonstrate the// setRawOffset()Â
import java.util.*;Â
public class GFG {Â
    public static void main(String[] args)    {Â
        // Create time zone object        TimeZone obj            = TimeZone.getTimeZone("Pacific/Pago_Pago");Â
        // Printing RawOffset value        System.out.println("Initially RawOffset is = "                           + obj.getRawOffset());Â
        // Setting RawOffset on object obj        obj.setRawOffset(6000000);        System.out.println("RawOffset "                           + "set to 6000000");Â
        // Printing RawOffset value        System.out.println("Current RawOffset is = "                           + obj.getRawOffset());    }} |
Output:
Initially RawOffset is = -39600000 RawOffset set to 6000000 Current RawOffset is = 6000000
Program 2:Â
Java
// Program to demonstrate the// setRawOffset()Â
import java.util.*;Â
public class GFG {Â
    public static void main(String[] args)    {Â
        // Create time zone object        TimeZone obj            = TimeZone.getTimeZone("Europe/Rome");Â
        // Printing RawOffset value        System.out.println("Initially RawOffset is = "                           + obj.getRawOffset());Â
        // Setting RawOffset on object obj        obj.setRawOffset(8000000);        System.out.println("RawOffset "                           + "set to 8000000");Â
        // Printing RawOffset value        System.out.println("Current RawOffset is = "                           + obj.getRawOffset());    }} |
Output:
Initially RawOffset is = 3600000 RawOffset set to 8000000 Current RawOffset is = 8000000
