Detailed Description

Timing service. Time is measured in ticks. A tick is about 10 msec.

Note that this is not suitable as a high-accuracy timing service. Timer events can be off by many ticks, and a tick may be slightly more or slightly less than 10 msec. Because of that, Timers are only intended for simple animation effects, input timeouts and similar things.
