[time-nuts] Radio Controlled Clocks

[Peter Vince]

Hello Andy,

     I have an old Maplin digital LCD clock for MSF, and that is always
about a second slow, but the Coopers analogue clocks are MUCH closer, as is
the Junghens DCF digital LCD clock.  But the Junghens DCF clock always
misses one or other of the DST changes!
