Pretty much every wifi transceiver is adc sampled so the frames are
"timestamped", but the adc sample time may not get pushed up.
The rtt/tof for the large umbrella of localization applications, I would
imagine will be impented even farther back in the rx chain.

Here is a ti app note with timestamping hardware wl8 but ordinary ap's with
no special protocol just timestamping the beacon frame.

Returning to the OP
"A TimeSync certification program will appear later this year, but
semiconductor firms will have to create new Wi-Fi chips including the
feature."
so this "new thing" will be hardware of some TBD form.

But more interest
