NTP: Why will my host NOT sync time to the NTP source

I have 3 V6.0 ESXi hosts in a V6.0 vCenter:

VMware ESXi 6.0.0 build-3380124
VMware ESXi 6.0.0 Update 1

I noticed the time on each host was out by varying amounts, in one case it was out by 15 minutes, so I checked the NTP settings via the GUI and they are set this way:

* Date & Time (in RED): 17:50 1/02/2021
* NTP Client: Running
* NTP Servers: 10.0.0.225, 10.0.0.226

I ran the command NTPQ in the ESXI shell and here's what I see:

remote refid st t when poll reach delay offset jitter
==============================================================================
DCadc03.bs 10.0.0.80 2 u 20 64 377 0.219 740086. 6.986
DCadc04.bs 10.0.0.80 2 u 20 64 377 0.318 740070. 11.974

So it seems to me that the NTP service on the host is set correctly (DCadc03 = 10.0.0.225, DCadc04 = 10.0.0.226) and from the offset, it looks like the time is 12.33 minutes slow.

So how do I force my hosts to sync to the time sources AND set their time to the same? NTPQ is showing a time difference!

I've tried restarting the NTP servers from the host's GUI a few times and it does not sync its time to the DCs. I checked the DCs and their time is correct.
