Heh, there's way too many. :)

/usr/share/zoneinfo on glibc systems has the support files for all the
timezones the glibc people know about.

The heirarchy is arranged by "major areas" having their own directories,
posix, SystemV, and 'right' directories for standardised names, and a
mess of 'old-style' names.

$ ls -F /usr/share/zoneinfo
Africa/      Chile/   Factory    Iceland      Mexico/   posix/      Univers=
al
America/     CST6CDT  GB         Indian/      Mideast/  posixrules  US/
Antarctica/  Cuba     GB-Eire    Iran         MST       PRC         UTC

$ ls -F /usr/share/zoneinfo/SystemV

$ ls -F /usr/share/zoneinfo/Canada/

Central   East-Saskatchewan  Newfoundland  Saskatchewan

etc etc...

This way, one can simply use: TZ=3DCanada/Pacific instead of trying to
get the right mixture of daylight savings time rules and correct offsets.

The tzset(3) manpage describes how you can create your own timezone
strings, in case you're not interested in having access to only the
timezones already on the system.
