user-1: Does Ripple use NTP or expect the nodes to do so?
If not, why not?  It seems that Ripple is a little more closed than your standard cryptocurrency, so this doesn't seem like an excessive demand.

user85: The Ripple server has SNTP support to tolerate system clocks that are inaccurate.
The consensus process also builds a consensus network time. Each validator pulls the consensus network time a bit closer to their local time. This consensus network time becomes the close times included in ledgers that support features like expiring cross-currency offers.
