[infinispan-dev] Time stamps in infinispan cluster

Hi How does the distributed clock work in infinispan/jboss cluster. Can some one please guide me. I have read a little bit about the total order messaging and vector clock. I have extended the infinispan API for freshness Aware caching. I have assumed the time is synchronized all the time and timestamps are comparable. But I want to know how the timestamp work in Infinispan in distributed environment, specially when the communication among the cluster nodes is in synchronous mode. Regards Meena
