Why doesn't the timeline on the main timers page show time I entered via the "Timesheet"?
When adding your time on the Timesheet entry page, you’re creating what we call "non-timeline time" - time that does not have a start and stop time.
Since there is no start and stop time, non-timeline time isn’t visible on the timeline itself.
Non-timeline time can be viewed by selecting a timer to expand it to show non-timeline time or by going to the "Timesheet" page. Non-timeline time is also added to the totals shown on each tab at the top of the main timers page.
