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

为了在文件名中使用数字日期的一个非常简单的解决方案，请使用以下代码:
set month=%date:~4,2%
set day=%date:~7,2%
set curTimestamp=%month%%day%%year%
rem then the you can add a prefix and a file extension easily like this
echo updates%curTimestamp%.txt
其他回答
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%
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。
@ECHO OFF

PAUSE
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=_

set FILENAME=database_dump_%logtimestamp%.sql

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。
