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
