There is the default timezone (UTC) which you can access with TimeZone.get ().
Others should be added by parsing some timezone definitions. AFAICS, LDML 
suggest using Olson naming and tzdata, so i suppose it is the way to go.

time_t is relative to the Epoch (00:00:00 UTC, January 1, 1970)... What would 
you want to do with it that you can't do with Bigints ?
