ok, so I made sure that my subvolume list on the servers is in the same order.
I had always listed the local volume first and the remote one second, 
but it sounds like this would lead to each node using it's own 
timestamps or do all the servers in the AFR elect a preferred 'first' subvol?

how about new files being replicated..  they'll get the timestamp of 
the server from which the source file is available?

in other words.. if I add a new empty volume, and AFR copies 
everything to it... what dates will be on the local files?

mine are using ntp, so, again, if they differ,it's by microseconds.
