Merged to master.
Thanks for your contribution.
> Use nano time in node failure detection.
> ----------------------------------------
>
> Key: IGNITE-13015
> URL: https://issues.apache.org/jira/browse/IGNITE-13015
> Project: Ignite
> Issue Type: Improvement
> Affects Versions: 2.8.1
> Reporter: Vladimir Steshin
> Assignee: Vladimir Steshin
> Priority: Minor
> Labels: iep-45
> Fix For: 2.9
>
> Time Spent: 40m
> Remaining Estimate: 0h
>
> Make sure node failure detection do not use:
> {code:java}
> System.currentTimeMillis()
> and
> IgniteUtils.currentTimeMillis()
> {code}
> We should use nano time instead. Disadventages of current impl.:
> 1) System time has no quarantine of strict forward movement. System time
> can be adjusted, synchronized by NTP as example. This can lead to incorrect
> and negative delays.
> 2) IgniteUtils.currentTimeMillis() is granulated by 10ms
> *To fix*:
> {code:java}ServerImpl.lastRingMsgReceivedTime{code} should be nano.
