Java get GMT Time

In this section, you will study how to obtain the GMT time.

GMT stands for Greenwich Mean Time and IST stands for Indian Standard Time. The following example helps you to obtain the IST and GMT time on the console. The method getDateTimeInstance() of class DateFormat provides the date and time format. Then we have used getTimeZone() method to get the time of both the zones. The method dateFormat.setTimeZone(zone) sets the time zone for the given date format.

Here is the code of GetGMTTime.java


import java.text.*;

import java.util.*;



public class GetGMTTime

{  

  public static void main( String[] args )  

  {  

  final int msInMin = 60000;  

  final int minInHr = 60;  

  Date date = new Date();  

  int Hours, Minutes;  

  DateFormat dateFormat = DateFormat.getDateTimeInstance( 

 DateFormat.LONG, DateFormat.LONG );  

  TimeZone zone = dateFormat.getTimeZone();  

  System.out.println( "IST Time: " + dateFormat.format( date ) ); 

  Minutes =zone.getOffset( date.getTime() ) / msInMin;  

  Hours = Minutes / minInHr;  

  zone = zone.getTimeZone( "GMT Time" +(Hours>=0?"+":"")+Hours+":"+ Minutes);

  dateFormat.setTimeZone( zone );  

  System.out.println( "GMT: " + dateFormat.format( date ) ); 

  } 

}
