It seems to me to be a bit easier to allow an arbitrary origin, so that the implementation doesn't have to track a zero time and subtract. Do some important applications require zero to be start of navigation? The issue is that there are situations where times the browser has to pass times to script that should be compared to navigation timing times and performance.now() times. So having a single timebase for all of these is a really good idea. See for example discussion in https://bugzilla.mozilla.org/show_bug.cgi?id=453650 about matching other timescales to performance.now() -Boris
