Parsing Java String into GMT Date

I'm trying to parse a String that represents a date using GMT, but it prints out in my timezone on my PC (pacific). When I run the below I get the below output. Any ideas on how to get the parse to parse and return a GMT date? If you look below I'm setting the timezone using format.setTimeZone(TimeZone.getTimeZone("GMT")); but its not producing the desired result.

output from below code:

Mon Oct 29 05:57:00 PDT 2012

 package javaapplication1;

    import java.text.ParseException;
    import java.text.SimpleDateFormat;
    import java.util.TimeZone;


    public class JavaApplication1 {

        public static void main(String[] args) throws ParseException {
            SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ssZ");
            format.setTimeZone(TimeZone.getTimeZone("GMT"));
            System.out.println(format.parse("2012-10-29T12:57:00-0000"));
        }
    }

You are using format.setTimeZone(TimeZone.getTimeZone("GMT")); in the formatter, which is being used in formatting the string into date ie

      Date date = format.parse("2012-10-29T12:57:00-0000");

is parsed treating 2012-10-29T12:57:00-0000 was a GMT value, but you are printing date which uses local timezome in printing hence you are noticing the difference.

If you want to print the date back in GMT , please use:

    String formattedDate = format.format(date);

and print the formattedDate . This will be GMT .

    System.out.println(formattedDate);

System.out.println(format.parse("2012-10-29T12:57:00-0000"));

Parses the date as GMT and returns a Date object. Then it prints it out (using the default toString()-method). This just uses the settings of your computer. so you should use:

Date parsedDate=format.parse("2012-10-29T12:57:00-0000");
System.out.println(format.format(parsedDate));

Complete working example

import java.text.SimpleDateFormat;
import java.util.Date;
import java.util.Locale;
import java.util.TimeZone;

public class Main
{
    public static void main(String[] args)
    {
        final SimpleDateFormat sdf = new SimpleDateFormat("dd-MM-yyyy hh:mm:ss z", Locale.ENGLISH);
        sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
        System.out.println(sdf.format(new Date())); 
        // ^^^ note printing the results of sdf.format() 
        //     not a raw `Date`
    }
}

result : 31-10-2012 08:32:01 UTC Note what I am actually printing out!
