GEO E111 Lecture Notes - Lecture 8: International Date Line, Leap Year
Document Summary
The time recorded in places within the same longitude. A longitude is an imaginary line running from n to s which shows how far e or w a place is from the prime meridian. Greenwich meridian (0 ) longitude is the point of reference when calculating time. Time is gained towards the e and lost towards the w. If the places are on the same side subtract the degrees to get the difference and add or subtract from the reference time depending on which side the place is. Time difference =12. 00-8=4 hours degrees=4 15=60 since x is behind in time its then 60 w. Standard time is time recorded by countries within the same time zone. Standard time was come up with due to confusion resulting from time changing at every longitude. The international date line it"s the 180 longitude.
