It is desirable but not required by any means. Slony-I will work as good 
with clocks that are a couple days apart as it would with clocks that 
are ntp synced in a LAN.

Some of the logging and status information, like the view that tells how 
far behind your replicas are, use timestamps generated on different 
servers for computation. That information will become a little hard to 
read if the clocks differ significantly. That's all.
