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.


The Amiga installation includes:
* Amiga guide and install instruction
* The Time Zone Database itself
* GUI to select local time zone
* SetClockGMT to adjust daylight-saving time
* ZDump to show time in other parts of the world
* Time Zone Library exposing database
* Support for localtime zone file
* Help files and documentation

To automatically adjust daylight-saving time a RTC module is required.
