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

使用%,当时间值为7-9时,您将遇到十六进制操作错误。为了避免这种情况,请使用delayeexpand并使用!min:~1!

如果你有PowerShell,另一个方法是调用它:

for /F "usebackq delims=Z" %%i IN (`powershell Get-Date -format u`) do (set server-time=%%i)

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%

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
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%

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。

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
