The app doesn't have to actually set the clock. If the app were modified to
keep track of a delta time value and use that for timing decisions, the actual
clock state is irrelevant.
The delta could be set by any of the aforementioned techniques.

That is an excellent idea.
A clock sync feature using WWV, WWVB, JJY, YVTO, CHU, DCF etc would
help those who don't have the ability to sync clock over the Internet.

Hello,
While using FT8 in a DXPedition setting, there may be conditions where
there is no reliable timing source for syncing of the system clock.
Bill,
When my Internet here in Costa Rica has been down, I've been able to sync my
system clock adequately closely by using WWV and using the Windows clock set
feature to set the clock, by simply setting to the next minute and then
clicking the Apply button as the time comes around to zero seconds. After
doing it a few times, you can nearly always get the hang of it and get it
within a second or so. Close enough that I've gotten by. It's a nuisance
and takes a bit of practice, but it can be done in a pinch. And it's gotten
me back on the air many times.
Per your request, though, I envision a clock set feature whereby you would
set the receiver to zero-beat WWV, and call a special clock set routine that
would look for the top-of-the-minute tone at the right audio frequency and
at approximately the top of the minute. When it sees the tone appear at the
right frequency, and at about the right time, it sets the system clock
accordingly. In my professional work, before the advent of the Internet, I
used hardware clocks based on such a system, and they seem to have worked
reasonably well most (though not all) of the time.
That would only work, however, in parts of the world where WWV is available.
When I lived in Africa many years ago, however, WWV was rarely audible, but
there was a different time signal that I could hear, a digital signal of
some sort, and I have no idea where it originated from (EU maybe?) or what
the protocol was. Something that uses that or other protocols might be
useful in those regions.
