[LIP] Time display in my choice of timezone using javascript

Hi,

I am trying to use javascript to show a timestamp in a webpage.

The timestamp is picked up by a new Date() object. Now, I need to
display this in a timezone of my choice, not the browser's. How do I
do that?

In Linux, I can do:

TZ=whatever date

and it will show me the date/time in timezone TZ.

I did code the whole damn thing myself in javascript, but it looks
kludgy - especially since the timezone I need to use requires DST
adjustments (US/Eastern).
