Here’s a good picture of a 24 hour analog clock in Venice.

Andy took this photo, and says:

…a clock just over the Rialto bridge. There is a flea market around you but if you turn and look up, there it is. Very strange as the hours don’t start/end where you would expect. I heard a strange story about this clock… I was told that the Venetians used to re-set the clock every day. When the sun rose, it was six o’clock. So at dawn, the clock was set to six. And that is where the clock sits now. It doesn’t run, or at least it wasn’t when I was there. Do you know if there is any truth to this?
