@echo off
setlocal
call :GetUnixTime UNIX_TIME
echo %UNIX_TIME% seconds have elapsed since 1970-01-01 00:00:00
goto :EOF

:GetUnixTime
setlocal enableextensions
for /f %%x in ('wmic path win32_utctime get /format:list ^| findstr "="') do (
    set %%x)
set /a z=(14-100%Month%%%100)/12, y=10000%Year%%%10000-z
set /a ut=y*365+y/4-y/100+y/400+(153*(100%Month%%%100+12*z-3)+2)/5+Day-719469
set /a ut=ut*86400+100%Hour%%%100*3600+100%Minute%%%100*60+100%Second%%%100
endlocal & set "%1=%ut%" & goto :EOF

The result will be returned into the first parameter passed to GetUnixTime, i.e. %UNIX_TIME%.
For example:

1341791426 seconds have elapsed since 1970-01-01 00:00:00

直接调用unix_time函数即可，调用方式已经给出了ie实例，还没有去验证，同学们可以自己去验证。

存成一个time2timestamp.bat,然后直接用就可以了
