The "--since=<time>" option of "git log" limits the commits displayed by the command by stopping the traversal once it sees a commit whose timestamp is older than the given time and not digging further into its parents. This is OK in a history where a commit always has a newer timestamp than any of its parents'. Once you see a commit older than the given <time>, all ancestor commits of it are even older than the time anyway. It poses, however, a problem when there is a commit with a wrong timestamp that makes it appear older than its parents. Stopping traversal at the "incorrectly old" commit will hide its ancestors that are newer than that wrong commit and are newer than the cut-off time given with the --since option. --max-age and --after being the synonyms to --since, they share the same issue. Add a new "--since-as-filter" option that is a variant of "--since=<time>". Instead of stopping the traversal to hide an old enough commit and its all ancestors, exclude commits with an old timestamp from the output but still keep digging the history. Without other traversal stopping options, this will force the command in "git log" family to dig down the history to the root. It may be an acceptable cost for a small project with short history and many commits with screwy timestamps. It is quite unlikely for us to add traversal stopper other than since, so have this as a --since-as-filter option, rather than a separate --as-filter, that would be probably more confusing.

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-<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 and Documentation/CodingGuidelines).
Those wishing to help with error message, usage and informational message
string translations (localization l10) should see po/README.md
(a po file is a Portable Object file that holds the translations).
To subscribe to the list, send an email with just "subscribe git" in the body to majordomo@vger.kernel.org (not the Git list). 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):
- 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
