i just installed ESXi servers. i have made the NTP settings but I am getting the error. i couldn't find what the problem was. can you help me if NTP is working or what is this warning?
VMware ESXi, 7.0.3, 19482537
vcenter Version: 7.0.3 Build: 19480866
Time Synchronization Services test
Configuration is not working normally.
Find the test result in the following textarea.

Verifying NTP service.

NTP is not synced
NTP never was synchronized.
Service analysis completed.
Try to Manual Setup the time on ESXi with the vCenter time and restart the NTP services.
ssh to the host
do an "ntpq -p" and post the output
[root@abc.local:~] ntpq -p
remote refid st t when poll reach delay offset jitter
==============================================================================
dfgdc.loc 10.34.20.11 4 u 52 64 3 0.734 -0.237 0.323
the value for reach is very bad (=3) , should be 377. maybe network problems
run "ntpq"
at the prompt type "as"
note the assid (second column)
run "rv <assid>"
post the output, also the content of /etc/ntp.conf
Did you ever find a solution? I have the same ESXi version but a higher vCenter version (19717403). Will be putting the cluster into production soon.
I read that another solution is to uncheck the "enable monitoring events" which will help.
TT
Please post the solution if you fixed the issue.
i am also looking for a solution...please share!
I have the same problem with unable to sync time via NTP.
My problem was that I have 2 kernel interfaces, but one to the internet and second to local network. But the internal one has checked "Management" service and Provisioning. If I removed Management from internal network, NTP works fine.
My issue was resolved by modifying the vcenter appliance to use UTC and pointed it at the same NTP server as the rest of the host. I had recently upgraded vCenter and it lost that setting.
