that server seems to be in holland (so am I) and it's not even giving me the correct
selection. my guess is they either set the TZ to the servers TZ or take some kind of guess (ip database?).
I would use javascript to determine the user's local TZ by comparing a timestamp
written into the javascript output with the current time given by the javascript Date object ...
you can then offer a pre-selected TZ value in a selectbox.
just a thought
