             Summary: DocumentNodeStore: required server time accuracy
                 Key: OAK-4030
                 URL: https://issues.apache.org/jira/browse/OAK-4030
             Project: Jackrabbit Oak
          Issue Type: Bug
          Components: documentmk
            Reporter: Julian Reschke


The DocumentNodeStore currently requires that the local time and the 
persistence time differ at most 2 seconds.

I recently tried to run a cluster with two Windows machines, and despite them 
being configured to use the same NTP service, they were still 4..5 s off.

 seems to confirm that by default, Windows can't provide the required accuracy.

One workaround seems to be to install custom ntp clients; but do we really want 
to require this?
