如何在 vim 中保存带有 UTC 时间的文件名?
我正在尝试保存包含日期和时间的文件名。但是,我希望日期和时间采用 UTC 格式。这就是我正在做的:
在 vimrc 中:
cmap <F3> <C-R>=strftime("%Y%m%d%H%M")<CR>
我在保存文件时键入此内容:
:w i<F3>.txt
并且我得到一个名为:的文件,
i[localtime].txt
但我想要:
i[UTCtime].txt
有没有办法真正做到这一点,或者我永远坚持我的当地时间? Vim 是我探索各个时区的唯一方法,请帮助我。 :)
哦,顺便说一下,我将同时使用 Linux 和 Windows。
I am trying to save a file name that includes the date and time. However, I would like the date and time to be in UTC. This is what I am doing:
In vimrc:
cmap <F3> <C-R>=strftime("%Y%m%d%H%M")<CR>
I type this when I save the file:
:w i<F3>.txt
and I get a file that is named:
i[localtime].txt
but I want:
i[UTCtime].txt
Is there a way to actually do this, or am I stuck with my local time forever? Vim is my only way to explore various time zones, please help me. :)
Oh and by the way, I will be using both Linux and Windows for this.

好吧,我不确定这是否能在 Linux 上正常工作,但我相信是这样的(我在 Mac 上)。
这个想法是,您可以使用
date
实用程序更灵活地检索时间。它接受一个选项-u
,该选项输出 UTC 时间。您所要做的就是将其包装在system()
调用中。在那里你就有了格式化的 UTC 时间。
如果插入的时间末尾出现空字符(显示为
^@
),那么您可能需要附加一个[:-2]
将其从返回字符串,位于上面映射中的
之前。它来自系统输出的翻译后的换行符。检查:h NL-used-for-Nul
。关于窗户,我不知道。在映射之前,您可能想在 Linux 中尝试一下该实用程序,但我几乎可以肯定不会有任何差异。
Well, I'm not sure whether this will work correctly on Linux or not, but I believe so (I'm on a Mac).
The idea, is that you can use the
date
utility to retrieve the time with more flexibility. It accepts an option-u
which outputs the time in UTC. All you have to to is wrap that in asystem()
call.And there you have your formatted UTC time.
If a null character appears at the end of the time inserted (it appears as
^@
) then you may want to append a[:-2]
to strip it from the returning string, right before the<CR>
in the mapping above. That comes from the translated newline the system outputs. Check:h NL-used-for-Nul
.About windows, well I have no clue. You may want to try out the utility in Linux before mapping things, but I'm almost sure there will be no differences.
