This is the sundial on the Queen Elizabeth School Hall, Godmanchester, Cambridgeshire.
I first saw the cat in the window, then the reflection of the sky on the window, I then realised that the sun dial is one hour fast and that the time was closer to 1.30 than 2.30.
Having looked at the time I took the shot I now realise that the camera's clock is also 1 hour fast.
