No matter what OS or platform you're on, counting the number of times 
your timer callback is called is *never* a good idea, even on desktop 
PCs. Timer callbacks can be skipped for any number of reasons (heavy 
system load, laptop suspend, etc).

If you look at the QML example code for Timer, they don't do that. They 
use Date() to get the current time. You should do something like that, 
too. Then your clock would always show the correct time (as long as it's 
running at all, at least).
