Basically, here is the "algorithm" for how we calculate duration in the timesheet dialog:
- A new Task flag ends the previous Task.
- A Break flag stops the previous flag also (and basically acts like a flag, except it doesn't provide all the same fields - just comment)
- A Note flag doesn't have any effect on duration and doesn't show up in the Timesheet dialog (and just allows comment)
- An End of Day flag is useful at the end of the day when you are not going to start another task (like in your case).
