Countdown timer for different timezones

[Dirk Hagemann]

Hi!

I'd like to implement a countdown timer on a webite. It should show the
months, days, hours, minutes and seconds until a given date and time.
So far it's not really difficult, but this website will be used from
different time zones, what will make a difference of 10 hours, if I use
the time-information from the client. The event will take place at one
fixed moment which is worldwide the same.

Does anyone know a way to solve this time-zone-problem?

Regards and thanks for your ideas
Dirk
