How To Quickly Calculate The Overtime And Payment In Excel?

i have a timesheet for work i need it to calculate total hours, overtime 1 and overtime 2
where hours from 07:00-15:00 is normal hours so no overtime counted
hours from 15:00-17:00 is counted in overtime 1
and all other hours is counted in overtime 2
like so
if A1(start time)=07:00 B1(end time)=19:00 C1(total hours)=12 D1(overtime1)=2 E1(overtime2)=2
or A1(start time)=04:00 B1(end time)=16:00 C1(total hours)=12 D1(overtime1)=1 E1(overtime2)=3

This is the formula i am using for overtime

 =IF(((C2-B2)+(E2-D2))*24>8, ((C2-B2)+(E2-D2))*24-8,0),
