Convert GMT to CST


In this section, you will learn to convert a GMT to CST format. The GMT stands for Greenwich Mean Time and CST stands for Central Standard Time.

Description of program:

This example helps you in converting a GMT time to CST time on the console. The SimpleDateFormat() constructor uses the given pattern and date format symbols. Here we use the date format as gmtFormat which gets converted to cstFormat. Then we have used  getTimeZone() method to get the time of both the zones to be converted. 

Central Time - USA + Canada

Central Standard Time (CST) = GMT-6
Central Daylight Time (CDT) = GMT-5

Here is the code of program:

import java.util.*;
import java.text.*;
import java.io.*;

public class GMTtoCST{
  public static void main(String args[]){
    Date date = new Date();
      DateFormat cstFormat = new SimpleDateFormat();
      DateFormat gmtFormat = new SimpleDateFormat();
      TimeZone gmtTime = TimeZone.getTimeZone("GMT");
      TimeZone cstTime = TimeZone.getTimeZone("CST");
      System.out.println("GMT Time: " + cstFormat.format(date));
      System.out.println("CST Time: " + gmtFormat.format(date));

Output of the program:

C:\unique>javac GMTtoCST.java

C:\unique>java GMTtoCST
GMT Time: 8/4/07 9:44 AM
CST Time: 8/4/07 4:44 AM
