How do I calculate hours beyond 23:59:59..!!

[magicharrington]

Hi

I am trying to enter a formula that will calculate, in hours, minutes and seconds, that will give me the duration between 2 incidents.
Example:

Start time 22:00:00 and End time of 04:30:30

The time difference between the incidents is 06:30:30 but I cannot get it to display correctly.
I then need to add up all the duration's between incidents and reformat to minutes only (which i have done by *1440) on another document

Can anyone please help with time calculation.
P.s I really dont want to reformat everything to incorporate dates too, just want it to recognize calculated duration's beyond the 24hr period

Thanks
Mark

=MOD(B1-A1,1) where a1 is start time b1 end time
