It is updated periodically to reflect 10changes made by political bodies to time zone boundaries, UTC offsets, 11and daylight-saving rules. 12 | 1README for the tz distribution 2 3"What time is it?" -- Richard Deacon as The King 4"Any time you want it to be." -- Frank Baxter as The Scientist 5 (from the Bell System film "About Time") 6 7The Time Zone Database (often called tz or zoneinfo) contains code and 8data that represent the history of local time for many representative 9locations around the globe.

| 13Here is a recipe for acquiring, building, installing, and testing the 14tz distribution on a GNU/Linux or similar host. 15 16To acquire the distribution, run the following shell commands: 17 18 mkdir tz 19 cd tz 20 wget --retr-symlinks 'ftp://ftp.iana.org/tz/tz*-latest.tar.gz' 21 gzip -dc tzcode-latest.tar.gz | tar -xf - 22 gzip -dc tzdata-latest.tar.gz | tar -xf - 23 24Alternatively, the following shell commands acquire the same 25distribution, with extra data useful for regression testing: 26 27 wget --retr-symlinks 'ftp://ftp.iana.org/tz/tzdb-latest.tar.lz' 28 lzip -dc tzdb-latest.tar.lz | tar -xf - 29 30Be sure to read the comments in "Makefile" and make any changes needed | 13See <https://www.iana.org/time-zones/repository/tz-link.html> or the 14file tz-link.htm for how to acquire the code and data. Once acquired, 15read the comments in the file 'Makefile' and make any changes needed |
