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
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

还有另一种简单的方法:
set HH=%time:~0,2%
if %HH% LEQ 9 (
set HH=%time:~1,1%
)
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
这个bat文件(保存为datetimestr.bat)生成3次datetime字符串:(1)长datetime字符串，包含星期几和秒， (2)短的datetime字符串没有它们和 (3)短版代码。
@echo off
REM "%date: =0%" replaces spaces with zeros
set d=%date: =0%
REM "set yyyy=%d:~-4%" pulls the last 4 characters
set yyyy=%d:~-4%
set mm=%d:~4,2%
set dd=%d:~7,2%
set dow=%d:~0,3%
set d=%yyyy%-%mm%-%dd%_%dow%
set t=%TIME: =0%
REM "%t::=%" removes semi-colons
REM Instead of above, you could use "%t::=-%" to
REM replace semi-colons with hyphens (or any
REM non-special character)
set t=%t::=%
set t=%t:.=%
set datetimestr=%d%_%t%
@echo Long date time str = %datetimestr%
set d=%d:~0,10%
set t=%t:~0,4%
set datetimestr=%d%_%t%
@echo Short date time str = %datetimestr%
@REM Short version of the code above
set d=%date: =0%
set t=%TIME: =0%
set datetimestr=%d:~-4%-%d:~4,2%-%d:~7,2%_%d:~0,3%_%t:~0,2%%t:~3,2%%t:~6,2%%t:~9,2%
@echo Datetimestr = %datetimestr%
pause
为了给予适当的赞扬，我将彼得·莫滕森(Peter Mortensen)(14年6月18日21:02)和欧佩罗(opello)(8月25日至11日14:27)的概念融合在一起。
您可以写得更短，但是这个长版本使阅读和理解代码变得更容易。

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，我需要使您的'set month=%date:~3,2%'如下所示::否则，00表示month
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%
