A lot of people use this to keep time after setting up NTP on their ESX box.. Myself I stick with the domain hierarchy which is default for Windows guests.

If you would like to play around with it feel free but be careful to not have to much of a time discrepancy between your guest and the domain controller as you will break Kerberos. If you are not in a domain environment it shouldnt matter.

Help me help you by scoring points.

What you said is perfect, but consider that you can also sync the Domain controller clock using VMTools, so you can't break kerberos.

I usually act in this way

- Update the esx host via NTP

- Using VMTools sync for both AD Client and AD Domain Controller

In this way I always have all clock perfectly sync together.

For non AD VM (client or DC) sometimes use VMTools Sync and sometimes use NTP from ESX or from an external source.

A bit confusing but what I do here is sync the PDC Emulator to an external time source and sync the ESX Host to the same source.

I use esxcfg-auth to allow for AD authentication so having my hosts with the same time as my DCs is very important.

I didn't understand it man. Still I want to know that why & why we r going for the synchronizing the Guest OS with the HOst OS.????

Because (only one from hundred possible other answers) you are not using a real cpu, and sometimes the virtual hardware clock fail.
