CMD日期更改日志

Question

我在制作一个程序，它有一个更改日志。程序更改日志必须说出版本，然后显示它多少天前。所以应该说：

[2013/03/19, 2 days ago] 

我用这个代码：

set versionreleasedate1=2013/03/17 
set /a verionday=%versionreleasedate1%-%date% 

echo Version: 1.0 BETA [2013/03/19, %verionday% days ago] 

但我知道之日起，将因CMD认为，\符号是devide买我想要的是一个小sepricator为日期。

所以它会像这样工作

set /a var1=2013/03/17-%date% (todays date) 

和回声多少天前。任何帮助将是非常感谢。

这工作对我的机器，并希望为您的：

@echo off &setlocal 
set "versionreleasedate1=2013/03/17" 
set "versionreleasetime1=00:00:00,00" 

call :GetInternational 
call :GetSecs "%versionreleasedate1%" "%versionreleasetime1%" startsec 
call :GetSecs "%date%" "%time%" stopsec 
set /a versionday=(%stopsec%-%startsec%)/86400 
echo Version: 1.0 BETA [%versionreleasedate1%, %versionday% days ago] 
goto :eof 

:GetInternational 
:: Sets a bundle of variables by reading the registry settings 
for /f "tokens=1,2*" %%a in (' reg query "HKCU\Control Panel\International"^|find "REG_SZ" ') do set "%%a=%%c" 
goto :eof 

:GetSecs "dateIn" "timeIn" secondsOut 
:: Output: Seconds elapsed since 1th Jan. 1970 00:00:00

setlocal 
set "dateIn=%~1" 
for /f "tokens=2" %%i in ("%dateIn%") do set "dateIn=%%i" 
for /f "tokens=1-3 delims=%sDate%" %%a in ("%dateIn%") do (
    if %iDate%==0 set /a mm=100%%a%%100,dd=100%%b%%100,yy=10000%%c%%10000 
    if %iDate%==1 set /a dd=100%%a%%100,mm=100%%b%%100,yy=10000%%c%%10000 
    if %iDate%==2 set /a yy=10000%%a%%10000,mm=100%%b%%100,dd=100%%c%%100 
) 
for /f "tokens=1-3 delims=%sTime%%sDecimal% " %%a in ("%~2") do (
    set "hh=%%a" 
    set "nn=%%b" 
    set "ss=%%c" 
) 
if 1%hh% lss 20 set hh=0%hh% 
if "%nn:~2,1%" equ "p" if "%hh%" neq "12" (set "hh=1%hh%" &set /a hh-=88) 
if "%nn:~2,1%" equ "a" if "%hh%" equ "12" set "hh=00" 
if "%nn:~2,1%" geq "a" set "nn=%nn:~0,2%" 
set /a hh=100%hh%%%100,nn=100%nn%%%100,ss=100%ss%%%100 
set /a z=14-mm,z/=12,y=yy+4800-z,m=mm+12*z-3,j=153*m+2,j=j/5+dd+y*365+y/4-y/100+y/400-2472633,j=j*86400+hh*3600+nn*60+ss 
endlocal &set "%~3=%j%" 
goto :eof 

endlocal 

％versionreleasedate1％&％versionreleasetime1％必须是喜欢％日期％&％TIME％您的机器上相同的格式！
