Setting a Default Zone for Timezone of America Region Example

The following example shows the usage of Java TimeZone setDefault(TimeZone) method to set the TimeZone to be returned by the getDefault() method. We've created a TimeZone using America/Los_Angeles and then set it to default using setDefault() method. Then using getDefault() method, we've verified the result.

package com.tutorialspoint;

import java.util.TimeZone;

public class TimeZoneDemo {
   public static void main( String args[] ) {

      // create time zone object 
      TimeZone tzone = TimeZone.getTimeZone("America/Los_Angeles");

      // set time zone to default
      tzone.setDefault(tzone);

      // checking default time zone
      System.out.println("Default time zone:" +tzone.getDefault());
   }    
}

Output

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

Default time zone:sun.util.calendar.ZoneInfo[id="America/Los_Angeles",offset=-28800000,dstSavings=3600000,useDaylight=true,transitions=185,lastRule=java.util.SimpleTimeZone[id=America/Los_Angeles,offset=-28800000,dstSavings=3600000,useDaylight=true,startYear=0,startMode=3,startMonth=2,startDay=8,startDayOfWeek=1,startTime=7200000,startTimeMode=0,endMode=3,endMonth=10,endDay=1,endDayOfWeek=1,endTime=7200000,endTimeMode=0]]

      // set time zone to default
      tzone.setDefault(tzone);

      // checking default time zone
      System.out.println("Default time zone:" +tzone.getDefault());
   }    
}

Output

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

Default time zone:sun.util.calendar.ZoneInfo[id="Africa/Abidjan",offset=0,dstSavings=0,useDaylight=false,transitions=3,lastRule=null]
