I think it's ridiculous to have a spec that defines a single method. It  
would make sense to fold this into the spec that defines the Performance  
interface:  
http://dvcs.w3.org/hg/webperf/raw-file/tip/specs/NavigationTiming/Overview.html

The spec says that the timer is accurate to at least a tenth of a  
millisecond, there's hardware that doesn't support that accuracy. It  
should say to be as accurate as possible, but is not required to be more  
accurate than a tenth of a millisecond.

The spec should call out whether the clock should be ticking while the  
document is not "fully active" (as defined in HTML).
