I have a simple test repository with just several commits and want to see the date&time filtered log:
$ git log --author="automatix" --since="2013-01-30" --pretty -- test commit ea0719bef142659fa561c9d040b2120012ed0184 Date: Thu Jan 31 02:03:12 2013 +0100 commit ab4a8387bc4d9bdb4f67212df77eb1fc3d8b6304 Date: Thu Jan 31 01:59:11 2013 +0100 commit a0b027beba2cd03571bb9475b9db9542f8efe990 Date: Thu Jan 31 01:50:38 2013 +0100 commit add77c8fe2ba9254c11b98e14facede3420dc51c Date: Thu Jan 31 01:48:34 2013 +0100 commit e6e323c05d37c74fcabeb9186b95c0d49b862e6f Date: Thu Jan 31 01:46:27 2013 +0100 commit 8c286391e54d3fc1e210950b1320fd6f013a8f84 Date: Thu Jan 31 01:41:27 2013 +0100 commit 9c880595e57f717383796fa2940f41f0f42f7e2a Date: Thu Jan 31 01:38:17 2013 +0100 commit a95527f36a533e1ecba1aadceea31a9dcbe1a8db Date: Thu Jan 31 01:30:00 2013 +0100
The first selected commit is a95527f36a533e1ecba1aadceea31a9dcbe1a8db
from 2013-01-30 01:30:00
. 8 commits are selected:
$ git log --author="automatix" --since="2013-01-30" --format=oneline -- test | wc 8 34 498
OK. Now I select since 2013-01-31
:
$ git log --author="automatix" --since="2013-01-31" --format=oneline -- test | wc 0 0 0
What? Ok, that should mean, that the since
rule excludes the commits of the startdate. Right?
But let's go on:
$ git log --author="automatix" --since="2013-01-31 01:30:00" --pretty -- test commit ea0719bef142659fa561c9d040b2120012ed0184 Date: Thu Jan 31 02:03:12 2013 +0100 commit ab4a8387bc4d9bdb4f67212df77eb1fc3d8b6304 Date: Thu Jan 31 01:59:11 2013 +0100 commit a0b027beba2cd03571bb9475b9db9542f8efe990 Date: Thu Jan 31 01:50:38 2013 +0100 commit add77c8fe2ba9254c11b98e14facede3420dc51c Date: Thu Jan 31 01:48:34 2013 +0100 commit e6e323c05d37c74fcabeb9186b95c0d49b862e6f Date: Thu Jan 31 01:46:27 2013 +0100 commit 8c286391e54d3fc1e210950b1320fd6f013a8f84 Date: Thu Jan 31 01:41:27 2013 +0100 commit 9c880595e57f717383796fa2940f41f0f42f7e2a Date: Thu Jan 31 01:38:17 2013 +0100 commit a95527f36a533e1ecba1aadceea31a9dcbe1a8db Date: Thu Jan 31 01:30:00 2013 +0100
$ git log --author="automatix" --since="2013-01-31 01:30:00" --format=oneline -- test | wc 8 34 498
Now, when I'm writing the starttime as well, the commits of the starttime are included .
I don't understand the logic. Can anybody explain, why it works so strange?
Thanks
In case it helps someone else who lands here like I did, after a bit of researching I found out that using ISO8601 format also works:
This will give you precision down to the second. Note: you can also use:
etc.
Of course, this doesn't "explain why it works so strange." However, it certainly solved the problem for me.
EDIT:
After a bit more research, I found out "why it works so strangely":
It turns out that when you don't specify a date format, git log defaults to either the author's timezone or commit dates, meaning for consistent behavior, it's useful to explicitly declare your date format with something like:
Lastly, when you don't specify a time, it defaults to your local time when you ran the command.
Long story short, being specific should solve the problem:
Also, you can set the default date format permanently with the following command:
you can use any one of these values:
(relative|local|default|iso|rfc|short|raw)
