I'd say define it as a minimum precision of 1ms, but browser manufacturers can define any precision they wish.

Do we need to offer any protections against CPU spinning? What if one browser (say the dominant market-leading browser at the time) implements this with timers that have a 15ms granularity? Consumers of this API using a 1ms timer still incur a 15ms delay. App programmers that don't test on browsers that do offer hi-res timers will spin the CPU. Since these browsers by definition are not market leaders, they'll be forced to re-introduce the clamp on the new API, and we'll be back where we started. Is there a way to avoid repeating history? Or am I missing something? :-) Mike On Thu, Oct 2, 2008 at 8:44 PM, Maciej Stachowiak <[EMAIL PROTECTED]> wrote: On Oct 2, 2008, at 8:27 PM, Cameron McCormack wrote: > Maciej Stachowiak: >> I think I will mention some of these possible variations when >> proposing the spec.
