在Windows批处理脚本中格式化日期和时间

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

@ECHO OFF
: Sets the proper date and time stamp with 24Hr Time for log file naming
: convention ('YYYYMMDD_HHMMSS')

: Scrapes the characters out of their expected permissions in the date/time
: environment variables.

: Expects a date format of '____MM_DD_YYYY'
: Expects a time format of 'HH:MM:SS' or ' H:MM:SS'

SET HOUR=%time:~0,2%
SET dtStamp9=%date:~-4%%date:~4,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2% 
SET dtStamp24=%date:~-4%%date:~4,2%%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%

::========================================================================  
::== 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。

希望这能有所帮助:

set MM=%date:~4,2%
set DD=%date:~7,2%
set YYYY=%date:~10,4%

echo %DD%_%MM%_%YYYY%

这将打印05_06_2021

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。

双击此批处理文件进行即时演示，命令提示符窗口将弹出并显示您的时间戳. . . . .
