在Windows批处理脚本中格式化日期和时间

Question

在Windows批处理脚本中格式化日期和时间在Windows（Windows XP）批处理脚本中，我需要格式化当前日期和时间，以便以后在文件名中使用等。它类似于Stack Overflow问题如何在批处理文件中附加日期，但也有时间。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  8:35:31.012009_07_28__ 8_36_01有没有办法允许％TIME％的单个数字小时，所以我可以得到以下内容？2009_07_28__08_36_01

Answer 1

我最终得到了这个脚本：

set hour=%time:~0,2%

if "%hour:~0,1%" == " " set hour=0%hour:~1,1%

echo hour=%hour%

set min=%time:~3,2%

if "%min:~0,1%" == " " set min=0%min:~1,1%

echo min=%min%

set secs=%time:~6,2%

if "%secs:~0,1%" == " " set secs=0%secs:~1,1%

echo secs=%secs%

set year=%date:~-4%

echo year=%year%

::在WIN2008R2上，例如我需要让你的'set month =％date：~3,2％'如下所示::否则00为MONTH出现

set month=%date:~4,2%

if "%month:~0,1%" == " " set month=0%month:~1,1%

echo month=%month%

set day=%date:~0,2%

if "%day:~0,1%" == " " set day=0%day:~1,1%

echo day=%day%

set datetimef=%year%%month%%day%_%hour%%min%%secs%

echo datetimef=%datetimef%

Answer 2

@ECHO OFF

: Sets the proper date and time stamp with 24Hr Time for log file naming

: convention

SET HOUR=%time:~0,2%

SET dtStamp9=%date:~-4%%date:~4,2%%date:~7,2%_0%time:~1,1%%time:~3,2%%time:~6,2% 

SET dtStamp24=%date:~-4%%date:~4,2%%date:~7,2%_%time:~0,2%%time:~3,2%%time:~6,2%

if "%HOUR:~0,1%" == " " (SET dtStamp=%dtStamp9%) else (SET dtStamp=%dtStamp24%)

ECHO %dtStamp%
