After opening a browser window,I tried calling javascript using alert(new Date()). It gave me the current date with current timezone. I then changed the timezone though the Date and Time Properties of Windows XP. When I try to run the same javascript, it gives me the old timezone.

Reproducible: Always

Steps to Reproduce:
1. Write a javascript within HTML with the following code:
alert(new Date());
2. Open it in firefox 3.
3. Change the computer's timezone through Date and Time properties by clicking on the time in the tray icons.
4. Refresh the page in firefox. It still shows the old timezone.
