It can't in Opera, since currentTime will always start at 0 (modulo bugs).  
Is there any browser that really intends to let currentTime start at an  
offset, and why? If so, I suppose that the seek knob will start somewhere  
in the middle and that any attempt to seek to before that point will just  
seek to that non-zero offset. That's a pretty weird UI and one reason I  
think the timeline should always be normalized, whatever the timestamps or  
other metadata of the resource itself says.
