Reception in many parts of the UK is very iffy indoors. It really needs
an external antenna.

<http://en.wikipedia.org/wiki/Time_from_NPL>

One of my clocks doesn't update daylight saving time until the
following day, which makes it useless on two days each year. It can't
even be set to show UTC only

Moral of that storey: done buy one until a few days before the setting
changes so it can be returned if necessary.

All being well, the wearers will spend at least some of their time
outdoors - enough to correct any minor error build-up.

It sounds as if you may have some local 60 KHz interference (analog TV
used to be a major problem, now it's switched-mode PSUs in equipment...).
MSF reception here is fine on many different clocks, as it was when the
transmitter was located in Rugby. You may also be able to received the
DCF77 signal from Germany.

Actually, if reception is that bad with you, perhaps you have a device
which is trying to receive a non-local signal?

Which aren't exactly cheap and might not dso the job.
IIRC there;s over 30,000 police officers even the cheapest watch is ~
£30.

Doesn;t solve vthe problem though.

Policeman arrives on at the scene of a crime, he and others want to
know what time he arrived.
So he looks at his watch whcih says 10am, trouble is when he got the
call he was in the cafe finishing breakfast
so can;t admit to arriving on the scene at 10am because he was meant
to be there at 9:45am so what time
does he report he was at the scene ?

Yes it is true I have two such radio clocks in my lab about 100ft
apart.
The times they displace are 4mins apart.
simialr to this (price and 'style' )

I have a weather centre which managers to get it;'s time setting from
Germany
everytime the clocks go back or forward, if I take the battery out and
reset it finds UK time.

Nah. it's called the speaking clock and charge it to the metropolitan
police

US signal for North America
MSF for the UK
DCF77 for Germany
(can't recall whether the Japanese one is back on the air as yet).

If your radio clocks don't work, move them away from the interference
source, and out of the basement! I expect you've already checked all this
out, though.

Is it fair to say its a crime that the chime is never on time.

"On or about," is a common phrase. It takes away the time issue and lets
one concentrate on the "whether it happened" issue.
