Calculate type - after the timer stops, in the event of a restart. The timer will not start. It will restart and delete the previous value. It will be restarted and leave the previous values in the archive.
First start - The timer will be started only 1 time. It will not restart. After the timer stops, its value is completely fixed. The timer ignores restart events.
Last start - The timer after restarting deletes its previous value. The timer always has 1 value that indicates the time of the last start.
Calculate all start and create archive - The timer after each restart saves the current timer to the archive and starts a new countdown. If the timer is restarted several times, all values and resolutions of the timers are saved.
Allow change goal after start - When the timer starts for the first time, it sets a target that is current at the current time. When subsequent events are triggered, the target will specify, which can lead to a re-calculation of time.
Update goal with issue update - The timer will respond to all changes in the task and will refine the goal.
