The problem is that WiFi uses a lot
What about converting an 'atomic clock' for this purpose?

Neat.
What does the Air Force use as a reference for GPS?
Other than WWVB-based frequency references/clocks that lock onto the 60
kHz carrier itself, I'm not aware of any WWVB-based clocks that were the
slightest-bit affected by format change (e.g. the addition of the
low-rate BPSK): Please point me to any references to the contrary if

Any brands to avoid?

Most of the atomic WWVB clocks cannot be set to zero time zone offset.
After considerable looking, I found one that can be set to GMT with DST
disabled. Look for this one:
Lacrosse Technology
Model WS-8016U
It also has local and RF remote temperature.
I got mine at Fry's Electronics, several
LaCrosse 8055 is one of the few wall clocks I know that allows UTC time
zone to be selected.
BTW, I have a Casio Waveceptor watch (the cheap $30 one) and it works
excellently, always acquiring WWVB signal at midnight to 2 AM here on East
Coast.

I bought the MFJ 121-B. Not LED, but I wasn't looking for that option.

Radio Shack used to have one, they may still have it, I have one, it
works fine it has cca 2 tall numbers for the time, and 0.75 tall for
the datum and temperature, Fries Electronics is selling one for USD35.--

Definitely avoid BRG clocks. They are reasonably priced and look really
nice on the outside but look like a high school science project inside.
Plus, with both versions I purchased (while at 2 different companies),
the IRIG-B option just didn't work reliably. It worked some of the
time,
I recently bought a La Crosse, See at ebay item 360752857574, that quickly
synced up to WWVB and, at least to my ability to mark a time tick, been
within the second of WWV. Total cost was $43.

CORRECTION:
The 8005 series (with indoor temperature) does not support GMT
Only the 8115 and 8119 series (with indoor and outdoor
temperature) support GMT.
