Can you not use GeoIP to find out where a user is connecting from, and select his time 
zone automatically for him/her ?
(Saves your conumdrum about how to display the choices)
Looks pretty accurate for me :

IP Address:
Country: Germany
Country code: DE
Region: 01
Longitude: 48.4667
Latitude: 8.9333
Status: Clear
Threat Level: 0

I have not looked further, but I would not be utterly surprised if there existed already 
some Java servlet filter or so to get the client's timezone automatically, and stuff it 
into some value which you can grab.
