Using NTP on VMs which do not support PTP

[Prateek Jain]

If I have a slice with VMs on sites which do not have PTP capability, can I use NTP (not PTP) to synchronise their clocks or the sites have to be PTP Capable to use NTP as well?

Hi Prateek,

Yes, you can use NTP to synchronize the clocks on VMs even if the sites do not have PTP capability. NTP and PTP are separate protocols for clock synchronization

Since NTP does not depend on PTP capabilities, you can deploy NTP on your VMs regardless of whether the sites support PTP. Just ensure that NTP is correctly configured on each VM to synchronize with reliable NTP servers.

@prateek. Arash is right on this. It all depends on what kinds of aplication and your experiment is. PTP is helpful when clock synchornization is needed down to a micro/milli second level  between multiple nodes that may or may not be geographically distributed.

Thanks Arash and Hussam!
