The ancient Babylonians set the numbers of hours, minutes, and seconds because their number system is based on the sexagesimal/60, so I think the Babylonians set these dates

It used to be very important. While latitude could be easily determined from the position of the stars, or teh sun, longitude was impossible to determine, without an accurate watch. so while captains knew their latitude very accurately , they had no idea of tehir longitude and often relied on a descxription of qweather patterns, coastlines, currents, fish, birds to try to figure out where they were, and of course often got lost :P\nThe problme was that since all clocks at that time were pendulum based, the motion of teh ship would dirupt the pendulum and make watches impossible on a ship. Until a british watchmaker invented a new type of pendulum tha t was imprevious to the ships motion, making teh british the foremost naval empire on the sea

Benjamin Franklin  was among the first Americans to discuss the idea of Daylight Saving Time. In fact, he proposed the idea while serving as U.S. minister to France as a way of conserving the cost of lighting for shops. The purpose has been to essentially utilize more of the daylight hours in spring and summer for daytime activities. Simply put, the Sun is up longer in the sky (rises earlier and sets later) in summer. Clocks and common mechanical timepieces keep what's called civil time, which roughly corresponds to the passage of a fictitious "average" Sun through our sky. This is necessary since the Sun does not rise and set on a regular basis, but changes by as much as 15 minutes throughout the course of the year.\n\nDaylight Saving Time was generally adopted by countries around World War I, but President Wilson repealed the United States' mandatory daylight savings law on March 31, 1918. During World War II, Daylight Savings Time was reestablished by law on a year-round basis, and later seen as a fuel saving measure during the Arab Oil Embargo crisis of 1973-74. In late 1974, standard time was brought back. During World War II, the U.S. and some other countries implemented "double" daylight savings time consisting of a two hour shift.

As has been noted, "o'clock" is short for "of the clock" meaning "according to the clock".  The fuller form of the expression is found as early as the late 14th century (in Chaucer).\nhttp://www.randomhouse.com/wotd/index.pperl?date=19970102\n\nBut we can perhaps go a bit further, to the origins of the mechanical clock itself and the very word "clock".  "Clock" comes from Latin 'cloca' meaning "BELL".  It was the term applied to the newer devices in use for measuring time in the thirteenth century.   As the word itself suggests, the key feature of these clocks is the bell that chimed the hours  In fact, these clocks, often set out in public in a tower to make it possible to notify everyone, did not necessarily have hands.       The key thing, then, was notifying people of the HOUR of the day (not the minute, and not, at least at first, the quarter or half hour either).  This practice of marking/announcing the hours is echoed by the watchman's call "nine o'clock and all is well."     Thus it is scarcely surprising that this way of expressing the time did not (and still does not, except in certain highly formal uses) state anything BUT the HOUR.\nhttp://en.wikipedia.org/wiki/Clock#A_new_mechanism\n\nSo you may picture the situation around 1300 -- the bell in the 'clock tower' strikes ONE time announcing that the hour is "one of ['according to'] the clock".

There is no use apart from being in time with the rest of the world.\n\nIn some parts it is not wise to put the clocks forward/backwards as this will change what time it is at the hottest in a day.\n\nChina is one of the few counties that does do this.

Originally, each town set its own local time and 12:00 noon was when the sun was highest in the sky. Thus the time in each town was different. When trains started running, this became annoying in trying to develop schedules. Time zones were created to standardize time over large areas.

The following website talks about the snooze button and several possible inventors. Also, it gives a history about the concept of needing a few extra 'zz's'. This website also refers to other websites about the snooze button. I found it very interesting. Hope that it will give you some helpful info. Good luck on your essay.\nhttp://www.thebluesmokeband.com/alarm.clocks.php

The History of Analog Clocks (SEE FIRST LINK BELOW) provides an explanation of the origin of the 24-hour day. The system dates back 4,000 years, to ancient Egypt and Babylon. \n\nEgyptian astronomers divided the night hours into 12 distinct sets of star patterns, which emerged over the horizon at roughly hour-long intervals. They divided the day into 12 hours to match, and because they lived near the equator, the days and nights were of roughly equal length throughout the year. \n\nThroughout the rest of the world, the 12 "hours" of the day and night were flexible depending upon the season. It wasn't until the 13th century A.D. that an Arab scientist named Abul-Hassan suggested the idea of clearly defined hours. \n\nIt's also worth noting that the number 12 is special in many cultures. For example, Egyptians counted in base 12. Dividing the day into two sets of 12 was a simple and elegant way of condensing the annual calendar into a day. \n\n*Repost*

For much of human existence, the shortest interval of time in common use was the day.  Thus, the first attempts to methodically measure time centered around the day.  Numerous calendars were invented to relate the day to the month, (which referred to the regular cycle of the Moon, hence the name month), and with the year, which referred to the regular cycle of the seasons, and, once it was noticed, the regular cycle of the sun's path in the sky getting higher and lower.  \n\nWhen it came to subdivisions of the day, at first people spoke of morning, midday, evening and night, as judged by the position of the sun.  Sometime around 5000 years ago, people in the Mideast and North Africa began to use devices that allowed them to more methodically subdivide the day.  The Egyptians divided the time between sunrise and sunset into twelve divisions, defining their "hour".  Of course, the length of their hour varied from day to day as the days got longer and shorter.  Hours could be measured methodically by use of a sundial or similar device.\n\nSubdivisions of the hour came about with the invention of devices like hourglasses or other devices that used the constant flow rate of some other fluid, like water, or that used a constant burn rate of something, like candle wax or incense.\n\nAttempts to measure short time periods, like minutes and seconds, came about later, and were first very crude.  Galileo used his pulse to time the period of oscillation of a pendulum.  Clocks using escapement type devices were developed in the 13th century.  The first pendulum clock appeared in 1656.  Since keeping time is essential to ocean navigation (specifically, comparing the local sun time with the reference time at a know location allows one to determine longitude), much effort went into improving mechanical clocks using escapements or pendula.\n\nIn the early 20th century, pendulum clocks gave way to quartz clocks, which used the regular vibrations of a quartz crystal in an electric field to produce a highly accurate sub-second timing device.\n\nThese clocks eventually gave way, for highly precise applications anyway, to clocks which use the natural oscillation frequencies of atoms like Cesium.

i would have thought that was obviouse..\n\nwhy do you have a key to the front door of your house?\n\nwhy do bank safes have time locks?\n\nwhy was the garder belt invented?\n\nthink of these and you may find your answer confucious...

Yes actually. When Ben Franklin was arguing with the Creator about his roll in the daily lives of men, he had to excuse himself because of an appointment. That lead to a discussion of time and time keeping, and God said he was partial to the old system where daylight was divided into twelve hours and so was the dark. Anyhow eventually the Lord suggested daylight savings time as a compromise.

It was invented during world war 2 to increase production. It was called "war time".  Basically instead of keeping to one time frame it has you start your day earlier in the summer and the "normal" time it would start in the winter by one hour.  The idea was that if someone got to work earlier in the summer they would hopefully stay a little later since there was still daylight.  It helped production by %5-10.

almost all of the world does.\nthe daylight savings time originated from Woodrow \nwilson.  he wast walking down the street and noticed that many people were using a tremendous amount of light after dark.  this was during wwi, the war to end all wars.  he included in his 14 point speech, which the 14th point is the point that made him most famous.  it outlined the league of nations, the predecessor to the united nations.
