I've since added this feature. It supports both the hard-to-read but 
pretty well-established ISO8601 duration syntax:


...and a slightly easier-to-read syntax:

   <time>4h 18m 3s</time>

Earlier in this thread I suggested maybe dropping <time> altogether, with 
a more generic replacement. Having tried that and gotten lots of negative 
feedback on the topic, I've since changed the spec again and we now have 
both a generic element for machine-readable data, <data>, as well as an 
element specifically for time-related machine-readable data, <time>.

The old <time> element, with its rendering rules and DOM API, are gone.
