How to format timestamp in GWT app with given timezone?

I have to format date/time in my gwt app with specific timezone, which is loaded from the server. Possible timezones are like this GMT, GMT+1, GMT-2 etc... Up to now i used DateTimeFormat to format my timestamps, and they used client's locale.

You can format in any timezone you want with DateTimeFormat, you just have to pass it as the second argument to the format method. And to obtain a TimeZone object, depending on how you want to present the timezone information (if ever) in the formatted date/time, you can use either createTimeZone(int) or createTimeZone(String) (getting the string out of TimeZoneConstants).
