The proposal for getting rid of HTL seems to be based on using time expired rather than hops expired, but doesn't that require a globally agreed time?

Ian.

No, I believe the agreed time isn't global---it's agreed just between two nodes at a time. I think the way Toad intends it to work is that instead of passing the number of hops-to-live, we pass the amount of time-to-live. When the next node routes to another node, it has to decrease the time-to-live so that it won't timeout before the routed node does. So there's no globally agreed time.
