The totals table reflects the organisation of your timers. In Tiller, time ‘flows up’ from child to parent.
This means if your structure is Client > Project > Task 1, and Client > Project > Task 2, and you tracked 30 minutes to Task 1, and 60 minutes to Task 2, the totals shown against both Client and Project will be 90 minutes.
Any timer which has time tracked against it can be expanded to view the relevant timeslots by clicking on the timer row.
From here, timeslot information can also be edited, including start time and date, end time and date, and any notes.
