Is there an alternative way to do timesync between servers

Is there an alternative way to do timesync between servers

Hello all,

I researched a lot but unfortunately couldn't find anything about it yet. Here is my issue.

We have several servers and we are monitoring them. 

  1.  We need to check that the time on the server is correct and NTP is running since a failure that will cause outages.

We know that using NTP to do timesync between servers should do the work but we wonder if is there any alternative way(other than NTP) to do this timesync with OpManager's some kind of service/feature . Please help us out with this. 

Thanks already, Regards.
