Java SimpleTimeZone setStartRule() Method
Description
The setStartRule(int startMonth, int startDay, int startTime) method is used to set the daylight saving time start rule to a fixed date within a month.
Declaration
Following is the declaration for java.util.SimpleTimeZone.setStartRule() method.
public void setStartRule(int startMonth, int startDay, int startTime)
Parameters
startMonth − The daylight saving time starting month.
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
Exception
IllegalArgumentException − This is thrown if the startMonth, startDayOfMonth, or startTime parameters are out of range.
Java SimpleTimeZone setStartRule() Method
Description

Declaration
Following is the declaration for java.util.SimpleTimeZone.setStartRule() method.
public void setStartRule(int startMonth, int startDay, int startDayOfWeek, int startTime)
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.
Return Value
NA
Exception

Java SimpleTimeZone setStartRule(int startMonth, int startDay, int startDayOfWeek, int startTime, boolean after) Method
Description
The Java SimpleTimeZone setStartRule(int startMonth, int startDay, int startDayOfWeek, int startTime, boolean after) method is used to set the daylight saving time start rule to a weekday before or after the given date within a month.
Declaration
Following is the declaration for java.util.SimpleTimeZone.setStartRule() method.
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
NA
Exception
IllegalArgumentException − This is thrown if the startMonth, startDay, startDayOfWeek, or startTime parameters are out of range.
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]
