  2. Write in ONLYBlack ink or PENCIL • What time zone do we live in? • How many time zones of the continental United Staes have? 1.      Use time zones in the United States or the International Date Line to interpret a map or representation of a globe and calculate current times in different places  (G-1A-M2) Oct. 5, 1862 ~ Calcasieu planters warned of arrival of Union troops in Lake Charles.

  3. Fact #1 Sun-timeUntil the 1860s most places in the world lived and worked on their own “Sun Time” which meant that everyone used sunrise and sunset as the time of day.

  4. Fact #2 Railroadschanged the way people thought about “time”. From 1883 railroads synchronized watches and created a “standard time”. 1.      Use time zones in the United States or the International Date Line to interpret a map or representation of a globe and calculate current times in different places  (G-1A-M2)

  5. Fact #3 World TimeThe world was divided into 24 time zones from east to west with the U.S. covering seven of those.

  6. Fact #4 U.S. Time zones Atlantic, Eastern, Central, Mountain, Pacific, Alaskan, and Hawaii-Aleutian. Our local TV is CST.

  7. Fact #5 Losing time If you travel from Lake Charles to DisneyWorld you will arrived one hour later than you left. 1.      Use time zones in the United States or the International Date Line to interpret a map or representation of a globe and calculate current times in different places  (G-1A-M2)

  8. Fact #6 Gaining time If you travel from Lake Charles to Disneyland in California you will arrived two hours before you left.

  9. Fact #7 LondonWhen time is it somewhere else? If it is 7AM in Lake Charles, what time is it in London? How do I find out?Memorized some chart? Call and wake them up? Google it?

  10. Fact #8 When is “today” not “today”? An imaginary line on the Earth's surface, 180° from Greenwich. As the Earth rotates, each day first begins and ends on the line. A traveler going east over the line sets their calendar back one day, and going west adds on day.

  11. Fact #9 When is it right now? Lets look at some places and tell when it is right now. • Beijing China

  12. Fact #10 Bet you didn’t know AM = Ante Meridiem, in 12-hour clock notation, Latin for "before noon" PM = Post Meridiem (p.m., "after noon") 1.      Use time zones in the United States or the International Date Line to interpret a map or representation of a globe and calculate current times in different places  (G-1A-M2) http://www.time.gov/timezone.cgi?Central/d/-6/java

  13. Fact #11 Universal Time The world is divided up into about 24 time zones. Standard time within most time zones is an integral number of hours offset from a time scale called Coordinated Universal Time (abbreviated UTC), maintained by a large number of very precise “atomic clocks” at laboratories around the world, including the U.S. Naval Observatory.
