Timing Events tied to clock.js.

ClockTimer is a subclass of Clock, which adds methods to handle timeout and intervals relying on Clock's ticks.

Why?

Once built-in setTimeout and setInterval relies on CPU load, functions may delay an unexpected amount of time to execute. Having it tied to a clock's time is guaranteed to execute in a precise way.

Here's a quote from W3C Timers Specification:

This API does not guarantee that timers will fire exactly on schedule. Delays due to CPU load, other tasks, etc, are to be expected.

API

Clock

• setInterval(handler, time, ...args) -> Delayed
• setTimeout(handler, time, ...args) -> Delayed

Delayed

• active -> Boolean - Is it still active?
• clear() -> void - Clear timeout/interval
• reset() -> void - Reset elapsed time
• (private) tick(deltaTime) -> void
• (private) execute() -> void
