>
> SLING-2967 fixed an issue where topology connectors were dependent on having
> machine clocks in sync - so inter-cluster we're no longer dependent on
> NTP-synching.
> Inside a cluster though, this problem is still there. Since heartbeats are
> written as absolute time - based on the originator's machine clock - it still
> only works fine the whole cluster is NTP-synched.
> In general I think this is not a problem as it is best-practice to make sure
> machines have NTP set up.
> Nevertheless, it would help if discovery.impl could become independent from
> this.
> Also, if clocks are off by too much, pseudo-network-partitions can occur,
> with the result of having multiple leaders in a cluster (also see SLING-3432)
