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

使用REG保存/修改/恢复对您的bat文件最有用的值。这是windows 7，对于其他版本，你可能需要一个不同的键名。
reg save "HKEY_CURRENT_USER\Control Panel\International" _tmp.reg /y
reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /d "yyyy-MM-dd" /f
set file=%DATE%-%TIME: =0%
reg restore "HKEY_CURRENT_USER\Control Panel\International" _tmp.reg
set file=%file::=-%
set file=%file:.=-%
set file

这个批处理脚本将完全按照O.P.的要求执行(在Windows XP SP3上测试)。
我还使用了前面“jph”所描述的聪明的注册表技巧，我认为这是在任何新的或旧的Windows系统上获得100%一致的日期格式“yyyy_MM_dd”的最简单方法。对一个注册表值的更改是瞬时、临时和微不足道的;它只持续几毫秒，然后立即恢复。

我最终得到了这个脚本:
set hour=%time:~0,2%
if "%hour:~0,1%" == " " set hour=0%hour:~1,1%
echo hour=%hour%
set min=%time:~3,2%
if "%min:~0,1%" == " " set min=0%min:~1,1%
echo min=%min%
set secs=%time:~6,2%
if "%secs:~0,1%" == " " set secs=0%secs:~1,1%
echo secs=%secs%
set year=%date:~-4%
echo year=%year%
在WIN2008R2上，例如，我需要使您的'set month=%date:~3,2%'如下所示::否则，00表示month
set month=%date:~4,2%
if "%month:~0,1%" == " " set month=0%month:~1,1%
echo month=%month%
set day=%date:~0,2%
if "%day:~0,1%" == " " set day=0%day:~1,1%
echo day=%day%
set datetimef=%year%%month%%day%_%hour%%min%%secs%
echo datetimef=%datetimef%
如果你不需要这个格式:
2009_07_28__08_36_01
然后你可以使用以下3行代码，使用%date%和%time%:
set mydate=%date:/=%
set mytime=%time::=%
set mytimestamp=%mydate: =_%_%mytime:.=_%
注意:字符/和:被删除，字符。空格被下划线取代。
示例输出(摄于8/5/15星期三下午12:49，时间为50秒93毫秒):
echo %mytimestamp%
Wed_08052015_124950_93
::========================================================================
::== CREATE UNIQUE DATETIME STRING IN FORMAT YYYYMMDD-HHMMSS
::======= ================================================================
FOR /f %%a IN ('WMIC OS GET LocalDateTime ^| FIND "."') DO SET DTS=%%a
SET DATETIME=%DTS:~0,8%-%DTS:~8,6%
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。
