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

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

REM Assumes UK style date format for date environment variable (DD/MM/YYYY).
REM Assumes times before 10:00:00 (10am) displayed padded with a space instead of a zero.
REM If first character of time is a space (less than 1) then set DATETIME to:
REM YYYY-MM-DD-0h-mm-ss
REM Otherwise, set DATETIME to:
REM YYYY-MM-DD-HH-mm-ss
REM Year, month, day format provides better filename sorting (otherwise, days grouped
REM together when sorted alphabetically).
IF "%time:~0,1%" LSS "1" (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-0%time:~1,1%-%time:~3,2%-%time:~6,2%
) ELSE (
SET DATETIME=%date:~6,4%-%date:~3,2%-%date:~0,2%-%time:~0,2%-%time:~3,2%-%time:~6,2%
)
ECHO %DATETIME%
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。

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。
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%
