timezone path

HP-UX (an SUSv3 compliant UNIX) uses textual rules in /usr/lib/tztab and the POSIX names like EST5EDT, CST6CDT, MST7MDT, PST8PDT. The file includes all of the historical rules for each time zone, akin to the Olson database.

NOTE: You should be able to find all of the timezones by inspecting the following directory: /usr/share/zoneinfo.

sunOS: /usr/share/lib/zoneinfo   /etc/TIMEZONE

AIX: /etc/environment
