There’s no excuse for not knowing the time in Venice. Many of the campi (squares) and calli (streets) have clocks mounted on a wall. Mind you, they may not display an accurate time, but we can’t have everything, can we?
Here is just a tiny sample. You’ll find many more the next time you’re there, I promise. It makes a change from spotting pissotte, anyhow!
And for those who need reminding, or have never encountered one, here is an example of a pissotta. (Ask me, if you don’t know what they are.)
