that's a lot of wakeups. Do you really need to do this?

There's a behavioural change not mentioned in the commit message :/

If I have a timer for 5 minutes and suspend after 1 minute for an hour    in the old code when we resume we will see a timer for 4 minutes left. In the new code we will see the timer has finished.

You can make an argument this is better, but it shouldn't be accidental. 
It's also not immune to timezone changes; we'd want this always in GMT.

*if* we want this behaviour the clock dataengine might be a good solution, that aligns itself to seconds automatically.
If we don't, maybe we want to neatly expose a QElapsedTimer; possibly updating a property on every QQuickWindow::beforeSyncronisation.
