What problem are you having? Have you tried using an input and event with a calculation?
Yes the code i have so far is:
input is "seconds"
'find the hours
hoursInteger = (hoursInteger + (seconds \ 3600)) Mod 1000
'find the minutes
minutesInteger = (minutesInteger + (secondsInteger + seconds) \ 60) Mod 60
'find the seconds
secondsInteger = (secondsInteger + seconds) Mod 60
when the time is at 0:59:59, and add 1 second I'm getting 0:0:0.
Also having trouble subtracting from the accumulated value.
