I have to tell you about the clocks at my work place. There are two battery operated wall clocks in here and about 10 days ago I came to work and they both had the wrong time displayed, so I duly let the caretaker know and he changed the batteries.
Two days after the battery change one of the clocks again had the wrong time displayed, about 3 hours slow and batteries were again changed. But every morning since then it has displayed the wrong time, always a couple of hours slow.
Yesterday that clock was 10 minutes fast and the other clock was 2 hours slow. Today the fast clock is 2 hours slow and the other one is 6 hours slow.
Dodgy clocks I hear you say. However, and this is where I can't figure out what is happening. All day the clocks keep time, but however many hours fast or slow. They don't speed up or slow down when the library is open, only overnight or the weekend. The library is shut when I leave and I put steel shutters over the doors and I open it up in the morning. No-one else except the caretaker has access.
I can't figure it out.
I have attached clock picture.
