Other clepsydras were cylindrical or bowl-shaped containers designed to slowly fill with water coming in at a constant rate. Markings on the inside surfaces measured the passage of hours as the water level reached them. Sun Clocks-Their moving shadows formed a kind of sundial, allowing people to portion the day into morning and afternoon The mechanical clock was a revolution of timekeeping. Atomic Clocks Times zones are regions of earth bounded by lines of latitude. The prime meridian Is the zero line of latitude is a given in the form of the equator, but for the longitude line was agreed on an international conference at Washington D.C in 1884 Toronto 12:00. London 8:00 pm, Moscow 11:00 pm, Tokyo 6:00 am the next day, Hawaii 6:00 am

Daylight Saving Time is a way of getting more light out of the day by advancing clocks by one hour during the summer. No we don't use this in Saskatchewan. No, there is not a year zero We are starting a new decade in 2011 Linear time is a concept where by time is seen sequentially, as a series of events that are leading toward something: beginning, and an end. I Time repeats it’s self in a cyclical motion In What Steve Miller song does time ‘keep slippin’ into the future’? Fly Like an Eagle.

__ Time travel agency __ The people in my group are Megan: Food, clothing and food, Carly: Goverment, religion, and why, and Shaylynn: Jobs, fun, and how. The state of civilization my group chose was Mesopatmia. The part of this that i am going to cover is **when: did this society begin? When did it end? When were significant key events? when was it t its peak? When was it at its worst?** and **where:was it located? This is where you have to include a map (this does not count as a page of your paper, this is separate. Please include in your paper where it was located then and now** ﻿ . The reason my group chose this one is because there was no other options left and we were forced to.
