negatif time...

hi

Code:

parseDate(&prod->tmbEndRun, date_rtu);   
parseTime(&prod->tmbEndRun, prod->htime_rtu_fin);           
printf("end %s\n", prod->htime_rtu_fin);

return me

Quote:

05/06/10
end 14:24:28

Code:

parseDate(&prod->tmbStartRun, date_rtu);   
parseTime(&prod->tmbStartRun, hactual_time);

return me

Quote:

05/06/10
start 14:31:03

now i would like to have duration between us....

Code:

prod->timeEndRun=mktime(&prod->tmbEndRun);
prod->timeStartRun=mktime(&prod->tmbStartRun);
prod->stopRun = difftime(prod->timeStartRun, prod->timeEndRun);

printf("stop run: %d %ld %ld\n",prod->stopRun, prod->timeStartRun, prod->timeEndRun);

that return me
stop run: -3205 1118428263 1118431468

why prod->timeStartRun (14:31:03) is smaller then prod->timeEndRun (14:24:28)?

thanks

The values are correct, but difftime returns double which doesn't print well with %d. %f should be better.
