[Sugar-devel] Time spent on activity (was Best time, format for logging?)

[Martin Abente]

IHMO, we should go for a "expect failure" approach.

If it closes properly, we add a new entry in the spent-time list with the
difference between the session started (not from the launches list) and the
current time. so it would be:

    [3600, 1800, 600]

In seconds, as we might have gadget-like activities that are only being
used shortly.

If it doesn't close properly, it gets discarded naturally. No complex logic.

The only "improvement" it occurs to me, is that we could "commit" this time
regularly... so even if its laptops shutdown we could still get some
not-so-garbage data.
