Only solution was a start up script that sets TZ on boot then does a time sync to an external source.

This seems to imply to me that setting the runtime clock from the
hwclock isn't happening properly when the system is rebooted.
This doesn't seem to be a timezone issue, as both hwclock and system
clock are both showing America/Pacific (based on the PDT/PST for Sep 14
and Dec 14 respectively).
So I would go look at how/when the system clock gets set from the
hwclock..

Then if I run ntpdate 192.168.50.246 (the IP of the AD DC), I am back to the
correct time:
hwclock Wed 14 Sep 2016 06:51:06 AM PDT -0.302285 seconds

Sure, because ntp updates the system (runtime) clock.

In ntp.conf and in chrony.conf I have:
server 192.168.50.246
But it lacks persistence. Chronyd service shows as loaded and active, but
it's not updating against the DC.

See above -- looks like the initial setting of the system clock isn't
happening from the hwclock. Most likely this is something from
systemd-timedated.
