7The Time Zone Database (called tz, tzdb or zoneinfo) contains code and
8data that represent the history of local time for many representative
9locations around the globe.  It is updated periodically to reflect
10changes made by political bodies to time zone boundaries, UTC offsets,
11and daylight-saving rules.
12
13See <https://www.iana.org/time-zones/repository/tz-link.html> or the
14file tz-link.html for how to acquire the code and data.
15
16Once acquired, read the leading comments in the file "Makefile"
17and make any changes needed to make things right for your system,
18especially when using a platform other than current GNU/Linux.
19
20Then run the following commands, substituting your desired
21installation directory for "$HOME/tzdir":
22
23	make TOPDIR="$HOME/tzdir" install
24	"$HOME/tzdir/usr/bin/zdump" -v America/Los_Angeles
25
26See the file tz-how-to.html for examples of how to read the data files.
27
28This database of historical local time information has several goals:
29
30 * Provide a compendium of data about the history of civil time that
31   is useful even if not 100% accurate.
32
33 * Give an idea of the variety of local time rules that have existed
34   in the past and thus may be expected in the future.
35
36 * Test the generality of the local time rule description system.
37
38The information in the time zone data files is by no means authoritative;
39fixes and enhancements are welcome.  Please see the file CONTRIBUTING
40for details.

42Thanks to these Time Zone Caballeros who've made major contributions to the
43time conversion package: Keith Bostic; Bob Devine; Paul Eggert; Robert Elz;
44Guy Harris; Mark Horton; John Mackin; and Bradley White.  Thanks also to
45Michael Bloom, Art Neilson, Stephen Prince, John Sovereign, and Frank Wales
46for testing work, and to Gwillim Law for checking local mean time data.
47Thanks in particular to Arthur David Olson, the project's founder and first
48maintainer, to whom the time zone community owes the greatest debt of all.
49None of them are responsible for remaining errors.
