Given the existence of dialup lines and international telephone
calls, that's going to be difficult to do 100%. Given the existence
of things like AOL (and other ISPs) web proxies, it's even harder
to do this 100%. You might manage to do "close enough", although
it wouldn't surprise me if quite a few people near a timezone
boundary who use dialup lines dial across the boundary.
Then there's the mobile wireless users.
Assuming that this is something the user DOESN'T WANT to spoof,
you could try asking the user what his time zone is, using your
best guess at the time zone as the default.
