Using Day Light Time for a SimpleTimeZone Instance of GMT Timezone Example

The following example shows the usage of Java SimpleTimeZone useDaylightTime() method to check if this time zone is in daylight saving time. We've created a SimpleTimeZone using GMT. Then we've checked date being in daylight savings using useDaylightTime() ethod and printed the status.

package com.tutorialspoint;

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 day light time  
      System.out.println("Use day light time : " + stobj.useDaylightTime());
   }      
}

Output

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

Use day light time : false

Using Day Light Time for a SimpleTimeZone Instance of BST Timezone Example

The following example shows the usage of Java SimpleTimeZone useDaylightTime() method to check if this time zone is in daylight saving time. We've created a SimpleTimeZone using BST. Then we've checked date being in daylight savings using useDaylightTime() ethod and printed the status.

package com.tutorialspoint;

import java.util.SimpleTimeZone;

public class SimpleTimeZoneDemo {
   public static void main( String args[] ) {
      
      // create simple time zone object
      SimpleTimeZone stobj = new SimpleTimeZone(820,"BST");

      // checking day light time  
      System.out.println("Use day light time : " + stobj.useDaylightTime());
   }      
}

Output

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

package com.tutorialspoint;

import java.util.SimpleTimeZone;

public class SimpleTimeZoneDemo {
   public static void main( String args[] ) {
      
      // create simple time zone object
      SimpleTimeZone stobj = new SimpleTimeZone(820,"IST");

      // checking day light time  
      System.out.println("Use day light time : " + stobj.useDaylightTime());
   }      
}

Output

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

Use day light time : false
