I went to Amble in Northumberland. Next to the harbour is this large modern sundial. The notice explaining sundials is very interesting. It explains why a sundial doesn't show perfect clock time. Part of that follows on from my previous post which noted that true sun-highest-in-the-sky midday is different in Wigton compared to London. This display panel also explains that the height of the sun in the sky (time of year) has an effect too. Click on the picture to enlarge it.
