Owners of these devices may find that they are not able to be

I see a problem here: they will know when it's 08:00 and that the
clock will become unreliable, but how will they know when it's 16:00
and that the clock has become reliable again?

They could wait till a couple of Seconds *after* 16:00 (as shown on
their Clock/Watch)?

Cos all Clocks & Watches that offer that "Atomic Synchronisation" thing
also Run as a normal (Quartz Crystal Controlled) Clock/Watch anyway,
don't they?

& a Quartz Crystal Controlled Clock/Watch maintains pretty Accurate
Time anyway (within a Second or so per Week, worst case & a Second
or so per Month or Year for good ones.

So that means that even when it's not been Synchronised with the Atomic
Clock, the Time that it Displays is still reasonably accurate.

Also, don't those Synchronised type things have a Symbol (or other
means of Identification) that shows whether (& when?0 it has been
Synchronised?
