Ooooh I like that one! The thread got a little confusing -- Are we talking about using NTP as a client on VMs? Or using VMs to run NTP servers? If as a server: Hell NAH! Don't do it. Like everyone said, the clock available to the OS isn't reliable, you don't want its drift to affect other machine's clocks. If as a client: Hell YAH! VM clocks are unreliable. Heck, we had a dedicated server that had a 14 second a day drift! We used the heck out of NTP to keep that sucker from losing time. Sort of related: I really love OVH as a hosting provider, but they offer one time source, and it is in Beauharnois, Canada, even if you use their Oregon US Datacenter. These NTP devices are so inexpensive to cover a whole datacenter, why are we introducing network latency?!? I am of the opinion that each physical datacenter should provide its own Stratum 1 NTP source. Beckman On Tue, 18 Feb 2020, Tim Bray via VoiceOps wrote:

How many NTP servers do you guys run? I just spun up two NTP servers in different locations on this network. Metaswitch just asked me for at least four (preferably five, or even more). Right now, the ones I have are just referencing the US pool. Eventually, they'll reference on-net GPS-backed devices.
