Configure vCenter Appliance to use NTP

When I installed vCenter appliance in the lab, I didn’t use a NTP server. (I know… STOOPID !!!) So how can you configure it afterwards ?


Login to the vCenter Appliance.

timesync.get will give you what mode the appliance is in.

ntp.server.add –servers <NTP Server> will add a NTP server

timesync.set –mode NTP will set the mode the NTP instead of host mode

ntp.get will give you the status of the NTP mode.
