Jeff King 6eced3ec5e date: use localtime() for "-local" time formats When we convert seconds-since-epochs timestamps into a broken-down "struct tm", we do so by adjusting the timestamp according to the known offset and then using gmtime() to break down the result. This means that the resulting struct "knows" that it's in GMT, even though the time it represents is adjusted for a different zone. The fields where it stores this data are not portably accessible, so we have no way to override them to tell them the real zone info. For the most part, this works. Our date-formatting routines don't pay attention to these inaccessible fields, and use the same tz info we provided for adjustment. The one exception is when we call strftime(), whose %Z format reveals this hidden timezone data. We solved that by always showing the empty string for %Z. This is allowed by POSIX, but not very helpful to the user. We can't make this work in the general case, as there's no portable function for setting an arbitrary timezone (and anyway, we don't have the zone name for the author zones, only their offsets). But for the special case of the "-local" formats, we can just skip the adjustment and use localtime() instead of gmtime(). This makes --date=format-local:%Z work correctly, showing the local timezone instead of an empty string. The new test checks the result for "UTC", our default test-lib value for $TZ. Using something like EST5 might be more interesting, but the actual zone string is system-dependent (for instance, on my system it expands to just EST). Hopefully "UTC" is vanilla enough that every system treats it the same. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>		2017-06-15 14:39:15 -07:00

Git - fast, scalable, distributed revision control system

Git is a fast, scalable, distributed revision control system with an unusually rich command set that provides both high-level operations and full access to internals.

Git is an Open Source project covered by the GNU General Public License version 2 (some parts of it are under different licenses, compatible with the GPLv2). It was originally written by Linus Torvalds with help of a group of hackers around the net.

Please read the file INSTALL for installation instructions.

Many Git online resources are accessible from https://git-scm.com/ including full documentation and Git related tools.

See Documentation/gittutorial.txt to get started, then see Documentation/giteveryday.txt for a useful minimum set of commands, and Documentation/git-.txt for documentation of each command. If git has been correctly installed, then the tutorial can also be read with man gittutorial or git help tutorial, and the documentation of each command with man git-<commandname> or git help <commandname>.

CVS users may also want to read Documentation/gitcvs-migration.txt (man gitcvs-migration or git help cvs-migration if git is installed).

The user discussion and development of Git take place on the Git mailing list -- everyone is welcome to post bug reports, feature requests, comments and patches to git@vger.kernel.org (read Documentation/SubmittingPatches for instructions on patch submission). To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org. The mailing list archives are available at https://public-inbox.org/git/, http://marc.info/?l=git and other archival sites.

The maintainer frequently sends the "What's cooking" reports that list the current status of various development topics to the mailing list. The discussion following them give a good reference for project status, development direction and remaining tasks.

The name "git" was given by Linus Torvalds when he wrote the very first version. He described the tool as "the stupid content tracker" and the name as (depending on your mood):

random three-letter combination that is pronounceable, and not actually used by any common UNIX command. The fact that it is a mispronunciation of "get" may or may not be relevant.
stupid. contemptible and despicable. simple. Take your pick from the dictionary of slang.
"global information tracker": you're in a good mood, and it actually works for you. Angels sing, and a light suddenly fills the room.
"goddamn idiotic truckload of sh*t": when it breaks
