Don't cut-quote my original message.

You can get the user's country using their preference, or from
Accept-Language HTTP header or using IP-to-geo mapping. If
Accept-Language header only contains the language not country (like
en, instead of en_gb), or that doesn't match with the country you can
guess from IP, you can dislpay both.

I know I'm not suggesting the solution that works for 100% of
situations, if the user wants to get the explicit list of all
timezones, you could always display them all with the checkbox or
something (like you can see on google calendar).

In an ideal world when a Canadian people uses French, the HTTP-Accept
header value would be fr_ca, instead of just fr. But even if it's just
'fr', wr can go back to the previous paragraph.
