timer IDs aren't spec compliant

[AlexandreBonaventure]

What is expected ?
According to spec, if I understand correctly, IDs returned by setInterval/setTimeout should be greater than zero. https://html.spec.whatwg.org/multipage/timers-and-user-prompts.html#timers

What actually happens ?
workerTimers.setInterval(cb) // return 0 the first time

This is actually a big discrepancy because (in my knowledge) it is a common practice to clear the interval/timeouts by doing:

function startTimer() {
  if (id) clearTimeout(id)
  setTimeout(cd, 1000)
}

This snippet would fail with your implementation but works with window.setTimeout

Hi @AlexandreBonaventure, thanks for making me aware of that discrepancy. The issue should be fixed in version 6.0.2.
