Declaration

Following is the declaration for java.util.SimpleTimeZone.setStartRule() method.

public void setStartRule(int startMonth,
                         int startDay,
                         int startTime)

  • startDay--The day of the month on which the daylight saving time starts.

  • startTime--The daylight saving time starting time in local wall clock time.

Return Value

NA

Example

The following example shows the usage of java.util.SimpleTimeZone.setStartRule()

package com.tutorialspoint;

import java.util.*;

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);
   }     
}

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]
