Best way to calculate employee attendance

[Guest]

Looking for the best way to calculate employee attendance based on when they
log in and out for the day. It has to compare to the employees start/end time
for each day of the week. Any suggestions?

Is it as simple as subtracting one time from the other or am I missin
the point

How do you subtract when the shift rolls over from one day to the next?
