We did discuss this a while ago when we decided to use ms here, and we thought it was quite reasonable. (I cannot recall the arguments, I'll have to dig up the issue.) There's also a limit of 2^14 on this, which will have to change if you wanted to go down to microseconds.

Thinking about this, I agree with @martinthomson: I don't think we should be opening up a design issue for consistency if it doesn't solve any other issues.

(FWIW, @ianswett, let's work on getting the extension accepted first before making changes in core spec to accommodate it.)
