my code as below

@echo off

if %DATE:~10,4%%DATE:~4,2%%DATE:~7,2% LSS 20091101 goto else
echo %date% > C:\Date.LOG
exit

goto endif

:else
echo "error! Date is incorrect!"
echo current date : %date%

@pause

:endif

from the code above, a LOG file with date inside it will be created.
now what i want to do is retrieve the date inside the log to replace my computer's date
(either the date inside the log file or the log file modified date)

anyone can help on this ?
thanks .

DATE <C:\DATE.LOG
