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.
Use day light time : false
Using Day Light Time for a SimpleTimeZone Instance of IST 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 IST. 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,"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
