TIME ZONES!

·  There weren’t always time zones… People used to set their clocks locally using the sun, This got too confusing, the train couldn’t keep its schedule

·  Greenwich would be 0° the middle of the zones

·  Each time zone has 15° longitude in between

·  The boundaries are not straight like lines of longitude, they zigzag

·  Time zones are directly related to degrees of longitude

·  The earth rotates once around every 24 hours (360 degrees / 24 hours)

·  STANDARD TIME was invented by a Canadian in 1884 (Sir Sandford Fleming)

·  The prime meridian is the centre of a time zone that extends 7.5 degrees of longitude to each side

·  Time in this zone is called UT (Universal Time) or GMT (Greenwich Mean Time)

·  The Earth rotates from west to east

·  Time zones in the Eastern hemisphere are ahead of UT

·  Time zones in the Western hemisphere are behind UT

Example: Ottawa is 5 time zones behind UT. If it is 12 noon in Greenwich, England it is 7 am in Ottawa.

·  The shape of time zones can be modified for political reasons or simple convenience

Example: China has one time zone but covers 60 degrees of longitude

Example: Canada has 6 time zones

·  The INTERNATIONAL DATE LINE is located at 180 degrees (West or East)

·  Opposite side of the planet from the Prime Meridian

·  If you cross over it going west you add a day

·  If you cross over it going east you lose a day

·  Some countries use DAYLIGHT SAVING TIME

·  Spring forward / Fall back

·  Extends time ahead in summer to allow for greater sunlight into the evening

·  Saves electricity as lights are not needed until later in the day
