SimpleDateFormatter shows wrong hour?

I want to get a string in the format of hhmm and uses SimpleDateFormatter for this purpose. My problem is that when the time is 1000 ms, it shows one hour ("01:00"). Have I missed something? The code that is below gives this result
>java TimeTest
what do I have to do to make it look like this instead:

The problem is that SimpleDateFormatter is converting the Date objects to your local time zone (if I ran your code, I'd see different values printed. You clearly live in Europe, maybe Norway or Sweden, right? -- one hour ahead of Great Britain).
If you adjust the time zone, you can get the results you want. Add a line like this to main():

and you'll be all set.

I have also tested to exchange the row
private static SimpleDateFormat hhmm_formatter = new SimpleDateFormat("HH:mm");
with this:
private static SimpleDateFormat hhmm_formatter = new SimpleDateFormat();
This is no difference.
Could it have something to do with that I'm in the +01 timezone (Sweden)? How can I avoid this localized time formatting?

Thanks Ernest!
Didn't see your answer before my previous post. Your line solved my problem.
And yes, I live in beautiful Sweden
