The system uses the standard hours (sum of day start and stop times, less break times) to calculate the total number of hours a piece of equipment is on the job on a normal day.

For example, if your workday begins at 08:00 and ends at 17:00 (9 hours), and you normally break for lunch from 12:00 – 1:00 (1 hour), the standard number of hours per day would be 8 (9–1=8).

On the day you transfer equipment to a job, the system calculates the usage hours by subtracting the later of the start time or ‘transfer in’ time from the workday stop time. It then subtracts the time for any breaks that occurred during that period.

For example, if your workday starts at 08:00 and stops at 17:00, and you transfer the equipment ‘in’ at 10:00, the system subtracts 10:00 from 17:00 (7 hours) because it is later than 08:00. Then, if you have designated a break time of 12:00 to 13:00 (1 hour), it subtracts that from the 7 hours to get a total of 6 hours for that day.

When calculating the usage hours for the ‘transfer out’ day, a similar method is used. The system subtracts the workday start time from the earlier of the ‘transfer out’ time or the workday stop time. It then subtracts the time for any breaks that occurred during that period.

To get the total number of hours a piece of equipment was on a job for a billing period, the system multiplies the standard number of hours per day by the number of full days (the days between the transfer in/out days), and adds them to the number of hours calculated for the transfer in/out days.
