Working out end time from start + elapsed

Hi,

I'm writing a script and have become stuck trying to define a variable (COMP) by adding an elapsed time (ELAPSE e.g 00:55) to a start time (START e.g 23:50).

Can anybody give me a solution as to how I can get a completion time in hh:mm from the variables above?

thanks

Richard

What shell?

If you use perl you could convert the output from the date command using time2str, do the same thing when script is complete and the simply subtract the two to get the differance in seconds. If you want to use perl I can send you an example.

Code:
#! /usr/bin/ksh

start=23:50
elapse=00:55

integer xh xm
typeset -Z2 compm comph

starth=${start%%:*}
startm=${start##*:} 

elapseh=${elapse%%:*}
elapsem=${elapse##*:}

((xh=starth+elapseh))
((xm=startm+elapsem))

if ((xm>60)) ; then
        ((xm=xm-60))
        ((xh=xh+1))
fi
((xh=xh%24))

comph=$xh
compm=$xm
comp=${comph}:${compm}
echo $comp
exit 0
