> Key: OAK-4030
> URL: https://issues.apache.org/jira/browse/OAK-4030
> Project: Jackrabbit Oak
> Issue Type: Documentation
> Components: doc, documentmk
> Reporter: Julian Reschke
> Assignee: Marcel Reutegger
> Priority: Minor
> Labels: documentation
> Fix For: 1.7.0, 1.8
>
>
> 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.
> https://blogs.technet.microsoft.com/askds/2007/10/23/high-accuracy-w32time-requirements/ 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?
