1. TIME ZONES – IT’S A TRIP! Watch it! http://www.youtube.com/watch?v=-j-SWKtWEcU (3 minutes)

2. TIME ZONES Sir Sandford Fleming, a Canadian railway surveyor and engineer, proposed an international system of time zones which was passed in 1884. There are 24 time zones around the world for the 24 hours it takes for the Earth to complete one full rotation (1 full spin on its axis).

3. LOCAL SUN TIME Prior to the establishment of time zones, most cities followed their own local sun times using a variety of tools, one of which was a sundial. Strangest Time Zones of the World https://www.youtube.co m/watch?v=uW6QqcmC fm8 (8 minutes)

4. LOCAL SUN TIME This worked for the most part when most travel times took a long period of time by horse or boat, but with the invention of trains which needed to be on a schedule for specific arrival and departure times, using local sun time was very inaccurate and confusing! So, largely due to rapid transportation via trains, a standard system of time was needed! First train to cross Canada – now located in Kingston, Ontario. Super speed magnetic train called the Maglev used in Japan, etc.

5. CANADA’S TIME ZONES Canada is a huge country that covers over 90 degrees of longitude from coast to coast. For this reason, it has six (6) different time zones. From east to west they are: 1) Newfoundland S. T. 2) Atlantic S. T. 3) Eastern S. T. 4) Central S. T. 5) Mountain S. T.6) Pacific S. T.

8. WHY AND HOW TIME ZONES CHANGE WHY: Since the sun appears to rise in the East, the East coast of Canada receives sunlight first. As a result, time is later in the East and earlier in the West. HOW: when moving towards the east, add (+) 1 hour for each time zone and when moving towards the west, subtract (-) 1 hour for each time zone. The one exception is Newfoundland where we only calculate a change of a ½ hour.

9. EXAMPLE When it is 12:00pm (noon) in Cambridge (Eastern Standard Time) what time will it be in: a)Atlantic S. T. = _____ (+ ___ hour) b)Newfoundland S. T. = _____ (+ _____ hours) c)Central S. T. = _____ (- ____ hour) d)Mountain S. T. = _____ (- ____ hours) e)Pacific S. T. = ______ (- ____ hours)
