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

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)

如前所述，只有在您知道当前用户使用的格式(例如，MM/dd/yy或dd-MM-yyyy，仅举两个例子)时，解析日期和时间才有用。这是可以确定的，但是当您完成所有的强调和解析时，您仍然会遇到使用了意想不到的格式的情况，需要进行更多的调整。
您还可以使用一些外部程序，它们将以您喜欢的格式返回日期段，但这样做的缺点是需要将实用程序与脚本/批处理一起分发。
也有批处理技巧使用CMOS时钟在一个相当原始的方式，但这是太接近裸线对大多数人来说，也不总是首选的地方来检索日期/时间。
下面是避免上述问题的解决方案。是的，它引入了一些其他问题，但就我的目的而言，我发现这是在现代Windows系统的.bat文件中创建日期戳的最简单、最清晰、最可移植的解决方案。这只是一个示例，但我认为您将看到如何修改其他日期和/或时间格式等。
reg copy "HKCU\Control Panel\International" "HKCU\Control Panel\International-Temp" /f
reg add "HKCU\Control Panel\International" /v sShortDate /d "yyMMdd" /f
@REM reg query "HKCU\Control Panel\International" /v sShortDate
set LogDate=%date%
reg copy "HKCU\Control Panel\International-Temp" "HKCU\Control Panel\International" /f
我今天遇到了这个问题，并解决了它:
SET LOGTIME=%TIME: =0%
它用0代替空格，基本上是零垫小时。
经过一些快速搜索，我没有发现它是否需要命令扩展(仍然使用SETLOCAL DISABLEEXTENSIONS)。
REM Assumes UK style date format for date environment variable (DD/MM/YYYY).
REM Assumes times before 10:00:00 (10am) displayed padded with a space instead of a zero.
REM If first character of time is a space (less than 1) then set DATETIME to:
REM YYYY-MM-DD-0h-mm-ss
REM Otherwise, set DATETIME to:
REM YYYY-MM-DD-HH-mm-ss
REM Year, month, day format provides better filename sorting (otherwise, days grouped
REM together when sorted alphabetically).
IF "%time:~0,1%" LSS "1" (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-0%time:~1,1%-%time:~3,2%-%time:~6,2%
) ELSE (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%
)
ECHO %DATETIME%
@ECHO OFF
