I can't think of a way to do that, since QTimer doesn't provide a way to 
query it for any kind of elapsed time.

It seems the only way to do that is what Diego and Thiago suggested. 
It's a bit surprising though that it took the Trolls to reach Qt 4.7 
until the need for a monotonic clock became apparent :P
