fast-import: add new --date-format=raw-permissive format There are multiple repositories in the wild with random, invalid timezones. Most notably is a commit from rails.git with a timezone of "+051800"[1]. A few searches will find other repos with that same invalid timezone as well. Further, Peff reports that GitHub relaxed their fsck checks in August 2011 to accept any timezone value[2], and there have been multiple reports to filter-repo about fast-import crashing while trying to import their existing repositories since they had timezone values such as "-7349423" and "-43455309"[3]. The existing check on timezone values inside fast-import may prove useful for people who are crafting fast-import input by hand or with a new script. For them, the check may help them avoid accidentally recording invalid dates. (Note that this check is rather simplistic and there are still several forms of invalid dates that fast-import does not check for: dates in the future, timezone values with minutes that are not divisible by 15, and timezone values with minutes that are 60 or greater.) While this simple check may have some value for those users, other users or tools will want to import existing repositories as-is. Provide a --date-format=raw-permissive format that will not error out on these otherwise invalid timezones so that such existing repositories can be imported.

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-<commandname>.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://lore.kernel.org/git/, http://marc.info/?l=git and other archival sites.
Issues which are security relevant should be disclosed privately to the Git Security mailing list git-security@googlegroups.com.
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):
