Track time spent
Tracker can keep a record of the time you spent on a task. Besides the assignee, other users can also record the time they spent.
To register the time spent:
Open the issue page.
Fill in Time spent.
If necessary, enter the start time and leave a comment. The comment will not be visible in the issue, but it will be saved in the Time Spent report.
Any user can record the time spent, not just the issue assignee. The Time Spent report stores information about who recorded time spent, and when.
View time spent
You can view the time spent on a task in the issue details (on the right panel), or in the Time Spent report.
If the Time spent section is not displayed in the issue details, add it:
Click Choose fields in the issue details panel.
Under Time Tracking, enable the Estimate and Time Spent options.
You can use the Estimate field to estimate the time needed to complete the task. Fill it in when you begin working on the task. Each time you record the time spent, the estimation will decrease by the amount you enter.
