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 %%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。

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%
这是我对adatetime字符串的2美分。在MM DD YYYY系统上切换第一个和第二个%DATE:~条目。

使用REG保存/修改/恢复对您的bat文件最有用的值。这是windows 7，对于其他版本，你可能需要一个不同的键名。
reg save "HKEY_CURRENT_USER\Control Panel\International" _tmp.reg /y
reg add "HKEY_CURRENT_USER\Control Panel\International" /v sShortDate /d "yyyy-MM-dd" /f
set file=%DATE%-%TIME: =0%
reg restore "HKEY_CURRENT_USER\Control Panel\International" _tmp.reg
set file=%file::=-%
set file=%file:.=-%
set file
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
