下面是如何生成一个日志文件名(基于http://ss64.com/nt/syntax-getdate.html):)

@ECHO OFF
:: Check WMIC is available
WMIC.EXE Alias /? >NUL 2>&1 || GOTO s_error

:: Use WMIC to retrieve date and time
FOR /F "skip=1 tokens=1-6" %%G IN ('WMIC Path Win32_LocalTime Get Day^,Hour^,Minute^,Month^,Second^,Year /Format:table') DO (
   IF "%%~L"=="" goto s_done
      Set _yyyy=%%L
      Set _mm=00%%J
      Set _dd=00%%G
      Set _hour=00%%H
      SET _minute=00%%I
      SET _second=00%%K
)
:s_done

:: Pad digits with leading zeros
      Set _mm=%_mm:~-2%
      Set _dd=%_dd:~-2%
      Set _hour=%_hour:~-2%
      Set _minute=%_minute:~-2%
      Set _second=%_second:~-2%

Set logtimestamp=%_yyyy%-%_mm%-%_dd%_%_hour%_%_minute%_%_second%
goto make_dump

:s_error
echo WMIC is not available, using default log filename
Set logtimestamp=_

:make_dump
set FILENAME=database_dump_%logtimestamp%.sql
...

也许是这样的:

@call:DateTime

@for %%? in (
    "Year   :Y"
    "Month  :M"
    "Day    :D"
    "Hour   :H"
    "Minutes:I"
    "Seconds:S"
) do @for /f "tokens=1-2 delims=:" %%# in (%%?) do @for /f "delims=" %%_ in ('echo %%_DT_%%$_%%') do @echo %%# : _DT_%%$_ : %%_

:: OUTPUT
:: Year    : _DT_Y_ : 2014
:: Month   : _DT_M_ : 12
:: Day     : _DT_D_ : 17
:: Hour    : _DT_H_ : 09
:: Minutes : _DT_I_ : 04
:: Seconds : _DT_S_ : 35

以下可能不是一个直接的答案，但一个接近的答案?

set hour=%time:~0,2%
if "%hour:~0,1%" == " " set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__0%time:~1,2%_%time:~3,2%_%time:~6,2%
else set datetimef=%date:~-4%_%date:~3,2%_%date:~0,2%__%time:~0,2%_%time:~3,2%_%time:~6,2%

至少这可能是鼓舞人心的。

一个很好的单行技巧是使用cmd /c echo ^%time^%来避免早期变量展开

cmd /c echo ^%time^% & dir /s somelongcommand & cmd /c echo ^%time^%

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

使用%，当时间值为7-9时，您将遇到十六进制操作错误。为了避免这种情况，请使用delayeexpand并使用!min:~1!

如果你有PowerShell，另一个方法是调用它:

for /F "usebackq delims=Z" %%i IN (`powershell Get-Date -format u`) do (set server-time=%%i)
