Observations

So yesterday, there I am in a group of about a dozen people taking part in a discussion about Time. We get onto Time Zones, the wiggly International Date Line, and then someone mentions something about Newfoundland being half-an-hour out of kilter, so I chime in with South Australia (half an hour behind New South Wales).

Heads nod all around me.

And how the city of Broken Hill in NSW is on Adelaide time because, well, Broken Hill is so darn CLOSE to Adelaide in South Australia and so far away from Sydney in NSW.

Heads nod all around me.

I segue into how the bathwater drains the other way round in the Southern Hemisphere. (hah hah!)

Heads nod all around me.

So I then mention that Sundials run the opposite way around in the Southern Hemisphere.

Heads shake in disbelief; a brief discussion follows.

How could the Sun possibly travel in the other direction Down Under. Itís THE SUN for heavenís sakes.

It is true!

Imagine yourself in, say, London UK looking at a sun-dial. You are facing the sun, facing south. The sun rises from the East, off to your left-hand side (just as it does in Toronto), travels from your left to your right across the sky and sets way beyond your right hand in the West.

Now imagine yourself where I used to live in Southern Cross in Western Australia. You are facing the sun, facing NORTH. The sun rises in the East, from your right-hand side, travels from your right to your left across the sky and sets way beyond your left hand in the West.

Now look down at the sun-dial in front of you in Southern Cross. The sun moves across the sky from your right to your left; the sunís shadow therefore travels from your left to your right, and goes around the sun-dial in an anti-clockwise direction.

Honest!
