Setting Start Rule with Month, Day and StartTime of a SimpleTimeZone Instance Example

The following example shows the usage of Java SimpleTimeZone setStartRule(int startMonth, int startDay, int startTime) method to set the daylight saving time start rule to a fixed date within a month. We've created a SimpleTimeZone using GMT and printed it. Then we've set the daylight saving time start rule using setStartRule() method and printed the updated SimpleTimeZone object.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.SimpleTimeZone;

public class SimpleTimeZoneDemo {
   public static void main( String args[] ) {
   
      // create simple time zone object
      SimpleTimeZone stobj = new SimpleTimeZone(820,"GMT");

      // checking initial value     
      System.out.println("Initial value: " + stobj);

      // setting start rule   
      stobj.setStartRule( Calendar.MAY, 2, 3600000);   

      // checking the new value      
      System.out.println("Final value : " + stobj);
   }     
}

Output

Let us compile and run the above program, this will produce the following result.

Initial value: java.util.SimpleTimeZone[id=GMT,offset=820,dstSavings=3600000,useDaylight=false,startYear=0,startMode=0,startMonth=0,startDay=0,startDayOfWeek=0,startTime=0,startTimeMode=0,endMode=0,endMonth=0,endDay=0,endDayOfWeek=0,endTime=0,endTimeMode=0]
Final value : java.util.SimpleTimeZone[id=GMT,offset=820,dstSavings=3600000,useDaylight=false,startYear=0,startMode=1,startMonth=4,startDay=2,startDayOfWeek=0,startTime=3600000,startTimeMode=0,endMode=0,endMonth=0,endDay=0,endDayOfWeek=0,endTime=0,endTimeMode=0]
