Show time in the Task Manager

[matthias-ronge]

Is your feature request related to a problem? Please describe.
If you test something, for example export, and it crashes, you can see that in the task manager. Or later, then it worked once. You can see that, too. After a while, the task manager is cluttered with similar entries, some are OK and some crashed, it is difficult to tell which was the last run.

Describe the solution you'd like
It would be nice to be able to display the times for tasks, when they started and when they stopped, and even better to be able to sort them by that, but that's optional.

Describe alternatives you've considered
Of course, you can always delete completed tasks in the Task Manager, but I would like to describe an idea of an improvement here.

Additional context
Task manager is part of the System and a displays tasks that are automatic.
