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
为了生成一个YYYY-MM-DD hh:mm:ss(24小时)时间戳，我使用:
SET CURRENTTIME=%TIME%
IF "%CURRENTTIME:~0,1%"==" " (SET CURRENTTIME=0%CURRENTTIME:~1%)
FOR /F "tokens=2-4 delims=/ " %%A IN ('DATE /T') DO (SET TIMESTAMP=%%C-%%A-%%B %CURRENTTIME%)
其他回答
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。
Windows中SET命令支持的offset:length格式将不允许您填充您似乎感兴趣的0。
但是，您可以编写一个BATCH脚本来检查小时是否小于10和 相应地用不同的回声字符串进行填充。
您将在此链接中找到关于SET命令的一些信息。
您还可以更改其他编程方法以达到此目的。
在unix bash (Windows上的Cygwin可用)中，只需说，
date +%Y_%m_%d__%H_%M_%S
它总是正确地填充。

也许是这样的:

@for %%? in (

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。
