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

还有另一种简单的方法:
set HH=%time:~0,2%
if %HH% LEQ 9 (
set HH=%time:~1,1%
)

@ECHO OFF
: Sets the proper date and time stamp with 24Hr Time for log file naming
: convention ('YYYYMMDD_HHMMSS')
: Scrapes the characters out of their expected permissions in the date/time
: environment variables.
: Expects a date format of '____MM_DD_YYYY'
: Expects a time format of 'HH:MM:SS' or ' H:MM:SS'
SET HOUR=%time:~0,2%
SET dtStamp9=%date:~-4%%date:~4,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2%
SET dtStamp24=%date:~-4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%
if "%HOUR:~0,1%" == " " (SET dtStamp=%dtStamp9%) else (SET dtStamp=%dtStamp24%)
ECHO %dtStamp%

我喜欢@The lorax上面的简短版本， 但对于其他语言设置可能略有不同。
例如，在德语设置中(使用自然日期格式:dd.mm.yyyy)，月份查询必须从4,2更改为3,2:
@ECHO OFF
: Sets the proper date and time stamp with 24h time for log file naming convention i.e.
SET HOUR=%time:~0,2%
SET dtStamp9=%date:~-4%%date:~3,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2%
SET dtStamp24=%date:~-4%%date:~3,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%
if "%HOUR:~0,1%" == " " (SET dtStamp=%dtStamp9%) else (SET dtStamp=%dtStamp24%)
ECHO %dtStamp%
: Outputs= 20160727_081040
: (format: YYYYMMDD_HHmmss; e.g.: the date-output of this post timestamp)
PAUSE
用斜杠分隔date命令的结果，然后可以将每个标记移动到适当的变量中。
FOR /F "tokens=1-3 delims=/" %%a IN ("%date:~4%") DO (
SET _Month=%%a
SET _Day=%%b
SET _Year=%%c
)
ECHO Month %_Month%
ECHO Day %_Day%
ECHO Year %_Year%
set hourstr = %time:~0,2%
if "%time:~0,1%"==" " (set hourstr=0%time:~1,1%)
set datetimestr=%date:~0,4%%date:~5,2%%date:~8,2%-%hourstr%%time:~3,2%%time:~6,2%
希望这能有所帮助:
set MM=%date:~4,2%
set DD=%date:~7,2%
set YYYY=%date:~10,4%
echo %DD%_%MM%_%YYYY%
这将打印05_06_2021
