Setting TimeZone in a Current Dated Calendar Instance Example

The following example shows the usage of Java Calendar setTimeZone() method. We're creating an instance of a Calendar of current date using getInstance() method and printing the time zone of the calendar instance. Then we're updating the date's timezone by using setTimeZone() method. In the end, updated time zone is printed.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.TimeZone;

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

      // create a calendar
      Calendar cal = Calendar.getInstance();

      // print current time zone
      String name = cal.getTimeZone().getDisplayName();
      System.out.println("Current Time Zone:" + name );
      TimeZone tz = TimeZone.getTimeZone("GMT");

      // set the time zone with the given time zone value 
      // and print it
      cal.setTimeZone(tz);
      System.out.println(cal.getTimeZone().getDisplayName());
   }
}

Output

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

Current Time Zone:India Standard Time
Greenwich Mean Time

Setting TimeZone in a Current Dated GregorianCalendar Instance Example

The following example shows the usage of Java Calendar setTimeZone() method. We're creating an instance of a Calendar of current date using GregorianCalendar() method and printing the time zone of the calendar instance. Then we're updating the date's timezone by using setTimeZone() method. In the end, updated time zone is printed.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.TimeZone;

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

      // create a calendar
      Calendar cal = new GregorianCalendar();

      // print current time zone
      String name = cal.getTimeZone().getDisplayName();
      System.out.println("Current Time Zone:" + name );
      TimeZone tz = TimeZone.getTimeZone("GMT");

      // set the time zone with the given time zone value 
      // and print it
      cal.setTimeZone(tz);
      System.out.println(cal.getTimeZone().getDisplayName());
   }
}

Output

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

Current Time Zone:India Standard Time
Greenwich Mean Time

Setting TimeZone in a Given Dated GregorianCalendar Instance Example

The following example shows the usage of Java Calendar setTimeZone() method. We're creating an instance of a Calendar of particular date using GregorianCalendar() method and printing the time zone of the calendar instance. Then we're updating the date's timezone by using setTimeZone() method. In the end, updated time zone is printed.

package com.tutorialspoint;

import java.util.Calendar;
import java.util.GregorianCalendar;
import java.util.TimeZone;

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

      // create a calendar
      Calendar cal = new GregorianCalendar(2022,8,27);

      // print current time zone
      String name = cal.getTimeZone().getDisplayName();
      System.out.println("Current Time Zone:" + name );
      TimeZone tz = TimeZone.getTimeZone("GMT");

      // set the time zone with the given time zone value 
      // and print it
      cal.setTimeZone(tz);
      System.out.println(cal.getTimeZone().getDisplayName());
   }
}

Output

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

Current Time Zone:India Standard Time
