Git 如何记录——自从计算？

我有一个简单的测试存储库，只有几个提交，并希望看到日期和时间过滤日志:

$ git log --author="automatix" --since="2013-01-30" --pretty -- test
commit ea0719bef142659fa561c9d040b2120012ed0184

commit a95527f36a533e1ecba1aadceea31a9dcbe1a8db
Date:   Thu Jan 31 01:30:00 2013 +0100

第一个选择的提交是来自 2013-01-30 01:30:00.8的 a95527f36a533e1ecba1aadceea31a9dcbe1a8db提交被选中:

$ git log --author="automatix" --since="2013-01-30" --format=oneline -- test | wc
8      34     498

好的。现在我从 2013-01-31开始选择:

$ git log --author="automatix" --since="2013-01-31" --format=oneline -- test | wc
0       0       0

什么? 好的，这应该意味着，since规则 不包括开始日期的提交。对吗？

但是让我们继续:

$ git log --author="automatix" --since="2013-01-31 01:30:00" --pretty -- test
commit ea0719bef142659fa561c9d040b2120012ed0184

$ git log --author="automatix" --since="2013-01-31 01:30:00" --format=oneline -- test | wc
8      34     498

现在，当我也编写起始时间时，起始时间的提交是 包括。

我不明白其中的逻辑，有谁能解释一下，为什么这么奇怪？

谢谢

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:

git log --since="2014-02-12T16:36:00-07:00"

This will give you precision down to the second. Note: you can also use:

git log --after="2014-02-12T16:36:00-07:00"
git log --before="2014-02-12T16:36:00-07:00"
git log --since="1 month ago"
git log --since="2 weeks 3 days 2 hours 30 minutes 59 seconds ago"

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:

git log --date=local

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:

git log --date=local --after="2014-02-12T16:36:00-07:00"

Also, you can set the default date format permanently with the following command:

git config log.date local

you can use any one of these values: (relative|local|default|iso|rfc|short|raw)
