I'm -0 on time and group; the use case is better satisfied by GML. But 
if you have to have it, it must be better specified than the georss 
point/line/polygon elements.

Look at Atom (or RSS) for example. There's no atom:dateTime. It's 
atom:published and atom:updated, with RFC 3339 values. Those specs state 
clearly what the time is all about. By comparison, georss:point (et al) 
are underspecified. Let's not repeat this mistake with time.

The georss:when proposed by Josh is a good start, but georss:duration 
reads better to me.
