更新:现在是2016年，我将使用PowerShell，除非有一个真正令人信服的向后兼容的原因，特别是因为使用日期的区域设置问题。参见@npocmaka的https://stackoverflow.com/a/19799236/8479
什么是Windows命令行语句(s)，我可以使用以我可以放入文件名的格式获取当前日期时间?
我想要一个.bat文件，它将一个目录压缩成一个归档文件，其中当前日期和时间作为名称的一部分，例如Code_2008-10-14_2257.zip。有什么简单的方法可以做到这一点，独立于机器的区域设置吗?
我真的不介意日期格式，理想情况下它是yyyy-mm-dd，但任何简单的都可以。
到目前为止，我已经得到了这个，在我的机器上给我Tue_10_14_2008_230050_91:
rem Get the datetime in a format that can go in a filename.
set _my_datetime=%date%_%time%
set _my_datetime=%_my_datetime: =_%
set _my_datetime=%_my_datetime::=%
set _my_datetime=%_my_datetime:/=_%
set _my_datetime=%_my_datetime:.=_%
rem Now use the timestamp by in a new ZIP file name.
"d:\Program Files\7-Zip\7z.exe" a -r Code_%_my_datetime%.zip Code
我可以接受这个，但它似乎有点笨重。理想情况下，它应该更简短，并具有前面提到的格式。
我用的是Windows Server 2003和Windows XP Professional。我不想安装额外的实用程序来实现这一点(尽管我知道有一些工具可以很好地格式化日期)。

我用vMax的批处理文件更改了答案，所以它也适用于荷兰语。
荷兰语(尽管我们是持久性的)在%date%、date/t和date中有一些更改，这些更改破坏了原始的批处理文件。
如果有些人也能检查其他Windows locale，并报告结果，那就太好了。
如果批处理文件在您的位置失败，那么请在命令提示符中包含这两个语句的输出:
回音:^ |日期
日期/ t
这是你应该从批处理文件中得到的输出示例:
C:\temp>set-date-cmd.bat
Today is Year: [2011] Month: [01] Day: [03]
20110103
以下是修改后的代码及其原因:
:: https://stackoverflow.com/questions/203090/how-to-get-current-datetime-on-windows-command-line-in-a-suitable-format-for-usi
:: Works on any NT/2k machine independent of regional date settings
::
:: 20110103 - adapted by jeroen@pluimers.com for Dutch locale
:: Dutch will get jj as year from echo:^|date, so the '%%c' trick does not work as it will fill 'jj', but we want 'yy'
:: luckily, all countries seem to have year at the end: http://en.wikipedia.org/wiki/Calendar_date
:: set '%%c'=%%k
:: set 'yy'=%%k
::
:: In addition, date will display the current date before the input prompt using dashes
:: in Dutch, but using slashes in English, so there will be two occurances of the outer loop in Dutch
:: and one occurence in English.
:: This skips the first iteration:
:: if "%%a" GEQ "A"
::
:: echo:^|date
:: Huidige datum: ma 03-01-2011
:: Voer de nieuwe datum in: (dd-mm-jj)
:: The current date is: Mon 01/03/2011
:: Enter the new date: (mm-dd-yy)
::
:: date/t
:: ma 03-01-2011
:: Mon 01/03/2011
::
:: The assumption in this batch-file is that echo:^|date will return the date format
:: using either mm and dd or dd and mm in the first two valid tokens on the second line, and the year as the last token.
::
:: The outer loop will get the right tokens, the inner loop assigns the variables depending on the tokens.
:: That will resolve the order of the tokens.
