TimeZone Class getOffset() method

Syntax:

    public abstract int getOffset(int era's , int yy, int mm, int dd, int DOW, int ms);
    public int getOffset(long dd);
  • getOffset() method is available in java.util package.
  • getOffset(int era's , int yy, int mm, int dd, int dow, int ms) method is used to return the time zone offset for current date updated when the mode is daylight savings time.
  • getOffset(long dd) method is used to return the offset of this time zone which is calculated from UTC at the given date (dd).
  • These methods don't throw an exception at the time of getting offset.
  • These are non-static methods and it is accessible with the class object only and if we try to access these methods with the class name then we will get an error.

Parameter(s):

  • In the first case, getOffset(int era’s , int yy, int mm, int dd, int dow, int ms)"
    • int era's – represents the era of the specified date.
    • int yy – represents the year of the specified date.
    • int mm – represents the month of the specified date.
    • int dd – represents the day of week of the specified date.
    • int dow – represents the year of the specified date.
    • int ms – represents the milliseconds in Standard Local Time.
  • In the second case, getOffset(long dd),
    • long dd – represents dates and it is represented in milliseconds.

Return value:

In both the cases, the return type of the method is int – It returns offset in ms to add default time zone (GMT) to return local time.

Example:

// Java program to demonstrate the example 
// of getOffset() method of TimeZone

import java.util.*;

public class GetOffsetOfTimeZone {
    public static void main(String args[]) {
        // Instantiates TimeZone object
        TimeZone tz = TimeZone.getTimeZone("Africa/Asmera");

        // Display tz
        System.out.println("tz: " + tz);

        // By using getOffset() method is to
        // get the offset according the given
        // arguments

        System.out.print("tz.getOffset(era's, yy, mm,dd,dow,time): ");
        System.out.println(tz.getOffset(1, 2009, 3, 3, 3, 100));

        // By using getOffset() method is to
        // get the offset according the given
        // date
        System.out.print("tz.getOffset(long d): ");
        System.out.println(tz.getOffset(Calendar.ZONE_OFFSET));
    }
}

Output

tz: sun.util.calendar.ZoneInfo[id="Africa/Asmera",offset=10800000,dstSavings=0,useDaylight=false,transitions=6,lastRule=null]
tz.getOffset(era's, yy, mm,dd,dow,time): 10800000
tz.getOffset(long d): 10800000
