git如何记录-自计数? [英] How does git log --since count?

问题描述

我有一个仅包含几次提交的简单测试存储库，并且想查看经过日期和时间过滤的日志:

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

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

第一个选择的提交是2013-01-30 01:30:00中的a95527f36a533e1ecba1aadceea31a9dcbe1a8db.选择了8个提交:

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

好.现在，我选择2013-01-31:

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

什么?好的，这意味着since规则排除了开始日期的提交.对吧?

What? Ok, that should mean, that the since rule excludes the commits of the startdate. Right?

但让我们继续:

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

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

现在，当我还要编写开始时间时，都会包含开始时间的提交.

Now, when I'm writing the starttime as well, the commits of the starttime are included .

我不明白逻辑.谁能解释，为什么它如此奇怪?

I don't understand the logic. Can anybody explain, why it works so strange?

谢谢

推荐答案

为防万一像我一样在这里着陆的人，经过一番研究，我发现使用

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"

这将使您精确到秒.注意:您也可以使用:

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"

等

当然，这并不能解释它为何如此奇怪的原因".但是，它无疑为我解决了这个问题.

Of course, this doesn't "explain why it works so strange." However, it certainly solved the problem for me.

经过更多研究，我发现为什么它如此奇怪":
事实证明，当您不指定日期格式时， git日志默认为作者的时区或提交日期，表示一致的行为，使用类似这样的显式声明日期格式很有用:

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

最后，如果您未指定时间，则默认为您运行命令时的本地时间.

Lastly, when you don't specify a time, it defaults to your local time when you ran the command.

长话短说，具体应该可以解决问题:

Long story short, being specific should solve the problem:

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

此外，您还可以使用以下命令永久设置默认日期格式:

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

git config log.date local

您可以使用以下任一值:(relative|local|default|iso|rfc|short|raw)

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