general/other Time Synchronization Issue with Different FreeBSD Versions on Nutanix AHV

[roomn]

Hello,
I am using FreeBSD as the Guest OS on a VM on Nutanix AHV.
When I run different versions of FreeBSD on the same Nutanix AHV cluster, the times on the two VMs become unsynchronized.
Could someone explain why this might be happening?

• AOS: 6.5.3

• VM
  • Guest OS: FreeBSD 12.1
  • Timezone (set during VM creation in Prism): Asia/Tokyo
  • Guest OS Timezone: JST-9 (output of tail -n1 /etc/localtime)
  • Result of date command: 9 hours ahead of the correct Japan time.
• VM2
  • Guest OS: FreeBSD 12.3
  • Timezone (set during VM creation in Prism): Asia/Tokyo
  • Guest OS Timezone: JST-9 (output of tail -n1 /etc/localtime)
  • Result of date command: correct Japan time

The conditions are the same except for the FreeBSD version.
I have observed the same phenomenon in FreeBSD versions 12.3 and later.
Both VMs were created using the following image: FreeBSD-XX.X-RELEASE-amd64.qcow2.xz from this link.[FONT=-apple-system][/FONT]

Nine hours ahead of "correct Japan time" is 18 hours ahead of Greenwich -- suggesting that one VM "system clock" had JST time rather than Greenwich time. For each host, please show us the full output of:

echo $TZ
tail -n1 /etc/localtime
cat /var/db/zoneinfo
TZ="" date
date
