It's supposed to be accurate to a second in a million years but how do they know

Checked that web site, looked up common faults, checked the batteries again, put them back in went to front door and pointed the rear of the clock towards North, and 2 mins 23 secs later the clock set itself, they have been working on transmitters overnight during July.

The two tall ones in the middle are. The first one could have been factory hospital or school etc. The furthest two are german and would more than likely been factory.
