Dave,

	What I had in mind was more a question of whether anyone uses
ICMP timestamps to measure network delay.  If so, then synchronization
is fairly important.  I've been playing with the idea of hacking
wiretap into ANSI-SPF, and timestamps would be a good way to divine
performance information.  However, it would require close synchro-
nization amongst the participants...
