However, I often have a laugh at the difference in time between
radio controlled clock, DAB clock and the internet bassed one
on the pc. Several seconds quite often. Who is right?

Any digitally based transmission system has latency.

But it is perfectly possible to compensate for that.

Each time the signal is processed it is delayed - even slightly. DAB is
a particularly bad offender - perhaps through using early technology.

A radio controlled clock should be pretty accurate at
the time of synchronisation. If the server is. I'd say.

time.is says that my smartphone is spot on. The PC is
a couple of seconds out and I have that synch daily.
