[time-nuts] Radio Controlled Clocks

[Andy Talbot]

I've just had a look around the house, and actually have four MSF clocks
and an old wristwatch minus its strap (antenna is a small ferrite rod
inside).  Forgot I had an old Junghans one as well - that is sitting out in
the shed as it requires a stronger signal than the more modern ones, and
seems to get better reception out there.   It's the only one that shows MSF
outages as it updates every hour - and the battery seems to last forever!
 I never checked to see how close that is to GPS;  if they implement proper
timing or just a simple delay bodge.
