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

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%

这个脚本使用一个WMI接口，主要通过WMIC工具访问，这是Windows的一个组成部分，因为Windows XP专业版(家庭版也支持，但默认情况下不安装该工具)。该脚本还通过创建和调用WSH vbscript来访问WMI接口，并以与WMIC工具提供的相同格式写入控制台输出时间，从而实现了缺少WMIC工具的解决方案。

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
当我需要一个日期/时间字符串时，我通常这样做:
set dt=%DATE:~6,4%_%DATE:~3,2%_%DATE:~0,2%__%TIME:~0,2%_%TIME:~3,2%_%TIME:~6,2%
set dt=%dt: =0%
这是为德国日期/时间格式(dd.mm。yyyy hh: mm: ss)。基本上，我将子字符串连接起来，最后将所有空格替换为零。
结果字符串的格式为:yyyy_mm_dd__hh_mm_ss
子字符串如何工作的简短解释:
%VARIABLE:~num_chars_to_skip,num_chars_to_keep%
因此，要想从“29.03.2018”这样的日期中得到年份，可以使用:
%DATE:~6,4%
^-----skip 6 characters
^---keep 4 characters
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
我是这样做的:
REM Generate FileName from date and time in format YYYYMMTTHHMM
Time /T > Time.dat
set /P ftime= < Time.dat
set FileName=LogFile%date:~6%%date:~3,2%%date:~0,2%%ftime:~0,2%%ftime:~3,2%.log
echo %FileName%
LogFile201310170928.log
