Time Configuration in VMWare
If I don't set the date and time correctly here, are all the virtual machines (unless they received date/time from domain controller NOT on this host) supposed to get the date and time from the host every day?

The reason for asking is that I received brand new DELL T320 server and set up VMware.
Not knowing about this "Time Configuration" section in ESX, I installed SBS2011 as VM.
But, the time on SBS2011 continuously 4 hours behind correct time every day even after I manually corrected it. I made sure that system BIOS clock was correct too.

>  the time on SBS2011 continuously 4 hours behind correct time every day even after I manually corrected it.

Is the SBS2011 configured in another time zone which just is 4 hours behind your local time?

Its really recommended to disable VM syncing with host.

1. Sync ESXi host with external time source

2. Disable VMware tools guest sync with host

3. Sync Windows VMs with PDC emulator in Domain

4. Sync PDC emulator eg DC with same time source as 1.

5. Sync Linux and Unix VMs with 1

"Is the SBS2011 configured in another time zone " --> I checked that already.

@Andy
I added NTP server name  pool.ntp.org like above screenshots. Is that good?

Yes, that's good, now your time on your ESXi server should be correct.

Follow the other Steps above.

Andy,
 
 Are you staying I completed Step 1, but need to following from Step 2 thru 5?
2. Disable VMware tools guest sync with host
3. Sync Windows VMs with PDC emulator in Domain
4. Sync PDC emulator eg DC with same time source as 1.
5. Sync Linux and Unix VMs with 1

Read up vmware timekeeping best practices
Basically it boils down to not using ESXi time but sync time in each guest
And in the other front synching ESXi time for better log co-relation and correct machine bootup clock.
