The following DOS batch file will set an environment variable to the number of seconds since midnight use it to time actions or to check if a given amount of time has passed the julian date can be used for calculations that pass midnight

echo sets an enviroment variable to hundredths of seconds since midnight
echo example call timesec SEC1 sets enviroment variable SEC1 to hundreds of seconds
echo also sets Jdate = julian date so %Jdate% can be used to determine number of days and if past midnight adjust seconds
echo takes 11/100 sec to run test with batch program:
echo "call timesec start & timeout /T 4 & timesec end & set /A delta= end - start & echo its %delta% versus 400"
echo "for seconds use set /A delta=(end-start)/100 also set /A hour=start/60/60/100 set /A min=start/60/100-hour*60"
:END
