NTP Calcru error time wnet backwards gone away!

[Supermule]

Hi

I had issues with a couple of pfsense VM's where a lot of calcru errors showed up and made the console unresponsive!

I run VM-tools 8.7.0.3046 and still the error came up. I use dk.pool.ntp.org as time server on both ESXi host and the VM.

I changed the timeserver in pfsense to use time.nist.gov and the calcru error disappeared and havent returned.

Both boxes run stable and console is responding with no errors!
