About
"What time is it?" -- Richard Deacon as The King
"Any time you want it to be." -- Frank Baxter as The Scientist
(from the Bell System film "About Time")
The Time Zone Database (often called tz or zoneinfo) contains code and
data that represent the history of local time for many representative
locations around the globe. It is updated periodically to reflect
changes made by political bodies to time zone boundaries, UTC offsets,
and daylight-saving rules.
Installation
* Copy tz.library to Libs:
* Assign ZONEINFO: to your zoneinfo directory
* Copy zoneinfo from tzdata.lha to ZONEINFO:
* Set TZ environment variable
* Validate installation with regression test tool
