Getting OffSet of Europe Timezone with given Inputs Example

The following example shows the usage of Java TimeZone getOffset(int era,int year,int month,int day,int dayOfWeek,int milliseconds) method to get the time zone offset, for current date, modified in case of daylight savings. We've created a TimeZone using Europe/Paris then printed the offset with given values.

package com.tutorialspoint;

import java.util.TimeZone;

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

      // create time zone object     
      TimeZone timezone = TimeZone.getTimeZone("Europe/Paris");

      // checking offset value       
      System.out.println("Offset value is :" + timezone.getOffset(1, 2011, 2, 2, 2, 300));
   }    
}

Output

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

Offset value is :3600000

Getting OffSet of Europe Timezone with given Date Example

   public static void main( String args[] ) {

      // create time zone object     
      TimeZone timezone = TimeZone.getTimeZone("India");

      // checking offset value for date      
      System.out.println("Offset value:" + 
      timezone.getOffset(Calendar.ZONE_OFFSET));
   }    
}

Output

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

Offset value is :0
