There is absolutely no guarantee how often #step will actually be 
called. The given #stepTime is just a recommendation to the system. To 
make your code work you should use something like:

	"Start the timer"
	timerStarted := Time totalSeconds.

	"Update my timer"
	self time: Time totalSeconds - timerStarted.
