Analyze and Edit Time
The Edit Time dialog allows you to enter in the duration data for the JIRA issue. You can edit the original estimate, remaining estimate or time spent values.
The Duration Analyzer will show you details on how it had calculated your task duration. This functionality can be helpful to determine/debug how your settings are affecting your JIRA data for time tracking.
The various calculation modes of The Connector can cause different duration values to get used. The advanced topic on Duration and Work describes in detail how these calculations are done.
