在Windows (Windows XP)批处理脚本中，我需要格式化当前日期和时间，以便以后在文件名等中使用。
这类似于堆栈溢出问题如何在批处理文件中添加日期，但也包含时间。
到目前为止，我有这个:
echo %DATE%
echo %TIME%
set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%
echo %datetimef%
这使:
28/07/2009
8:35:31.01
2009_07_28__ 8_36_01
是否有一种方法可以允许%TIME%中的个位数小时，以便我可以得到以下结果?
2009_07_28__08_36_01

当我需要一个日期/时间字符串时，我通常这样做:
set dt=%DATE:~6,4%_%DATE:~3,2%_%DATE:~0,2%__%TIME:~0,2%_%TIME:~3,2%_%TIME:~6,2%
set dt=%dt: =0%
这是为德国日期/时间格式(dd.mm。yyyy hh: mm: ss)。基本上，我将子字符串连接起来，最后将所有空格替换为零。
结果字符串的格式为:yyyy_mm_dd__hh_mm_ss
子字符串如何工作的简短解释:
%VARIABLE:~num_chars_to_skip,num_chars_to_keep%
因此，要想从“29.03.2018”这样的日期中得到年份，可以使用:
%DATE:~6,4%
^-----skip 6 characters
^---keep 4 characters

这个脚本使用一个WMI接口，主要通过WMIC工具访问，这是Windows的一个组成部分，因为Windows XP专业版(家庭版也支持，但默认情况下不安装该工具)。该脚本还通过创建和调用WSH vbscript来访问WMI接口，并以与WMIC工具提供的相同格式写入控制台输出时间，从而实现了缺少WMIC工具的解决方案。

因此，%DATE%的问题在于它依赖于区域设置。所以之前的大部分答案对我来说都不适用。如果你对确切的格式不挑剔，只是想要一个时间戳来区分文件，你可以这样做:
set _date=%DATE%-%TIME%
set _date=%_date:/=-%
set _date=%_date: =-%
set _date=%_date::=-%
set _date=%_date:.=-%
echo %_date%
这应该适用于大多数地区。如果它没有添加另一行，则设置_date=%_date:<offending_char>=-%以删除有问题的字符。例如:一个与文件名不兼容的字符或文件名中不希望出现的字符。
请注意，这并不符合问题所规定的确切标准。

第一行输出的格式与时区无关: 20150515150941.077000 + 120 这样，您只需按照自己的愿望格式化输出即可。
创建一个名为“search_files.bat”的文件，并将下面的内容放入该文件中。然后双击它。临时的%THH%变量被放置在适当的位置来处理AM。如果时间的前两位数字为0,Windows将忽略LOG文件的其余文件名。
