I would also mention to avoid two sources of truth.
I have seen people use NTP in the Guest & use VMware Tools ability to sync to the ESXi host.
This can become a battle for truth, as the VMware tools might correct to host time. If host time is too far off, then the drift settings may not allow it to correct.
you'll also notice problems in logging as time stamps move around, or jobs not working correctly.
So just make sure to do either NTP in the guest on its own OR no guest NTP, VMware Tools to ESXi host, then Host sync to NTP time servers.
Personally, I prefer the latter of those two options as it reduces the amount of configuration going into a specific virtual machine.
