wxTimer is not intended to be used this way. It is only approximate. It 
gets integrated with the event loop, and can be off by a fair bit, 
depending on how long it takes to process other events.

What you can do is use a wxTimer to get event approximately when you 
want them, and then, when handling that event check the system clock to 
see how much time has really passed. For an example, see the AnalogClock 
code in the demo.
