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

当前回答

for /f "tokens=1-4 delims=/ " %%I in ("%DATE%") do set curdate=%%K_%%J_%%I
for /f "tokens=1-4 delims=:," %%I in ("%TIME: =0%") do set curtime=%%I_%%J_%%K
echo %curdate%__%curtime%

如果您的系统使用另一个替换delims符号(用于切片到%%I,%%J…) 如果您的系统使用另一个D/M/Y订单,也可以编辑curdate

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
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%

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
...

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)

你可以用这些…

Parameters:
%date:~4,2% -- month
%date:~7,2% -- days
%date:~10,4% -- years

%time:~1,1% -- hours
%time:~3,2% -- minutes
%time:~6,2% -- seconds
%time:~9,2% -- mili-seconds

%date:~4,2%%date:~7,2%%date:~10,4% : MMDDYYYY
%date:~7,2%%date:~4,2%%date:~10,4% : DDMMYYYY
%date:~10,4%%date:~4,2%%date:~7,2% : YYYYMMDD
