pike.git/lib/modules/Calendar.pmod/tzdata/README:1: + README for the tz distribution    -  + "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. +  + See <https://www.iana.org/time-zones/repository/tz-link.html> or the + file tz-link.html for how to acquire the code and data. Once acquired, + read the comments in the file 'Makefile' and make any changes needed + to make things right for your system, especially if you are using some + platform other than GNU/Linux. Then run the following commands, + substituting your desired installation directory for "$HOME/tzdir": +  +  make TOPDIR=$HOME/tzdir install +  $HOME/tzdir/usr/bin/zdump -v America/Los_Angeles +  + Historical local time information has been included here to: +  + * provide a compendium of data about the history of civil time +  that is useful even if not 100% accurate; +  + * give an idea of the variety of local time rules that have +  existed in the past and thus an idea of the variety that may be +  expected in the future; +  + * provide a test of the generality of the local time rule description +  system. +  + The information in the time zone data files is by no means authoritative; + fixes and enhancements are welcome. Please see the file CONTRIBUTING + for details. +  + Thanks to these Time Zone Caballeros who've made major contributions to the + time conversion package: Keith Bostic; Bob Devine; Paul Eggert; Robert Elz; + Guy Harris; Mark Horton; John Mackin; and Bradley White. Thanks also to + Michael Bloom, Art Neilson, Stephen Prince, John Sovereign, and Frank Wales + for testing work, and to Gwillim Law for checking local mean time data. + Thanks in particular to Arthur David Olson, the project's founder and first + maintainer, to whom the time zone community owes the greatest debt of all. + None of them are responsible for remaining errors. +  + ----- +  + This file is in the public domain, so clarified as of 2009-05-17 by + Arthur David Olson.
