public void setStartRule(int startMonth,
                         int startDay,
                         int startDayOfWeek,
                         int startTime,
                         boolean after)

Parameters

  • startMonth − The daylight saving time starting month.

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

  • startDayOfWeek − The daylight saving time starting day-of-week.

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

  • after − If true, this rule selects the first dayOfWeek on or after dayOfMonth. If false, this rule selects the last dayOfWeek on or before dayOfMonth.

Return Value

Example

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

Live Demo
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,"US");

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

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

      // 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 = US,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 = US,offset = 820,dstSavings = 3600000,
useDaylight = false,startYear = 0,startMode = 3,startMonth = 4,startDay = 2,
startDayOfWeek = 2,startTime = 3600000,startTimeMode = 0,endMode = 0,
endMonth = 0,endDay = 0,endDayOfWeek = 0,endTime = 0,endTimeMode = 0]dMonth = 0,
endDay = 0,endDayOfWeek = 0,
endTime = 0,endTimeMode = 0]
