How does Mylyn count the active time for a task?
Whenever you work on a task, Mylyn accumulates the time you spend actively working on a task. This time can be viewed in the Personal Planning section of the Task Editor. When you are not interacting with Eclipse, the timing automatically times out after 3 minutes by default. This means that activity outside of Eclipse will not be captured when you work on the task and that the timings in Mylyn are a lower bound of the total time spent on the task (capturing timings for work done outside of Eclipse involves OS specific extensions).
