Difference between Total time and Reported time
When you build a report, you can notice that there are two columns that can show the tracked time: Total time and Reported Time. What is the difference between them?
Total Time shows all reported time into a task, project, by a user or any other column next to it. It does not depend on the period that you select in your report.
Reported time shows time that was submitted within the period of your report, i.e. this week, last month, etc.
Let's look at this screenshot as an example.
My period is Today. But Total 9:46 shows all the time I spent on this task, not just for today. The time I spent on it today is 5 hours.
