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.

Atomic.exe is a run once utility, which allows you to change of frequently
Windows checks in with a time server. Once the frequency is set, it
remains set.
