Once again I've seen people complaining that children aren't being taught to read analogue clocks. The technology is largely obsolete. Go to K-mart and have a look at the clocks on display. Digital is cheap and reliable. Nobody has a sundial except as a decorative measure. Sundials worked straight off the sun and as the length of the day changes from season to season needs a mental adjustment to use & I'm sure that less than 1 in a 1000 people would have the slightest clue how to adjust the value showing on the dial to match the local time.
