touble with a time calculation

[richard]

OT_Hours = 0 OT_Minutes = 0 OT_Seconds = 0
#stop clock here for the test otherwise sec/min rollovers during if tests will give incorrect results
if Hours > set_hour then OT_Hours = Hours - set_hour
if Minutes > set_Min then OT_Minutes = Minutes - set_Min
if Seconds > set_sec then OT_Seconds = Seconds -set_sec
#resume clock

note hour rollover to next day is not taken into account
