Daylight savings time was invented by Benjamin Franklin as a way for people to have more productive days. In the summer we "borrow" an hour from the morning and stick it onto the end of the day so that the long summer days are even longer.

The stopwatches are known as "Decimal Minute Watches"\nand are used in time-motion studies.  \n\nMost of the ones you can buy today are digital, but I did find pictures at the site below.

The first electronic calculation device using binary logic was built by Konrad Zuse in 1938. Check out the first link below.\n\nCharles Babbage built or at least conceived the first mechanical difference engines that could sort punch cards and even be programmed by punchcards.

In a modern clock, a voltage is applied to a crystal such as quartz.  This causes the molecules in the crystal to vibrate at a fixed frequency.  A sensor then counts the vibrations over time and determines how much time has elapsed.

Actually, me too!  I look at the clock all the time-- morning and night, and it's 9:11!  I thought, it's amazing.  I went through a period of about 6 months whenever I looked at the clock, it was specifically that time.  I thought maybe it was just in sync with my biological clock, but I couldn't shake the significance of those numbers.  I'm not sure what it all means-- but I do not believe in coincidences.  It's something worth looking into, definitely.  I'll be interested to find out your results.

A clock and a sundial?

This is where convention comes in. hehe.\n\nYou see, today "time" is defined based on a reference. We define one second as exactly 9,192,631,770 oscillations or cycles of the cesium atom's resonant frequency, replacing the old second that was defined in terms of the Earth's motions.\n\nThe "uncertainity" is due to the fact that our one second here ( where its based on the measurement of this number of oscilations )  is NOT 100% the same as compared to our measurement of one second based on the previous way.\n\nWhat was the previous way? Well, it bascially defines one second the other way around. What i mean here is that in the old days time is defined relative to the motion of the earth around the sun. Ancients defined the total time taken for the earth to finish one complete revolution around the sun as one year. Then they agreed that one year is approximately made up of 365 days. Each day is then divided into 24 hours. 1 hour is then considered as having 60 minutes where 1 minute comprises as 60 seconds.\n\nOf course to achieve the definition of time as how we have it now did not just come overnight. It took some time... hehe. I did not attempt a chronological development of the idea but just intend to shed some light on the subject. You can find further information on the link below.

I turned my daughter's clock forward today. She was not impressed with me when she eventually realised that she had got up at 5am instead of 6 to go to work. Ha.\n\nAlso have a look at the response OneRunningMan gave to The Kimster  on the same subject.

Coordinated Universal Time.  The UTC acronym was a compromise between English & French.\n\nUTC was formerly known as GMT (Greenwich Mean Time), and is called Zulu by the military and for aircraft operations (at least in the US, not sure about elsewhere).

do you mean tha YA website is lacking clock? To keep up with the time, for people that doesn't have the same time zone with Yahoo?

Hmm, what's this strange word o'clock?  The OED has this to say about its usage and origin:\n\n    (The hour of the day is expressed by a cardinal numeral, followed by a phrase which was originally  a. of the clock, now only retained in formal phraseology; shortened subsequently to  †b. of clock,  †c. a clock (see A prep.2),  d. o'clock, the current modern form; rarer obs. variants were †e. at the clock, and clock simply.)\n\nOf the clock strikes me as pretty similar to on the clock.  Does Deford disapprove of the use of o'clock in (2)?  Given that (1) means unambiguously the same thing, o'clock is redundant in that context in a way that on the clock isn't in the sports context, but people still say it all the time.  Would he try to stamp out this pernicious usage if he ruled the world instead of merely sports?  Fortunately, we'll never find out, because he's not the boss of us.

a clepsydra is more commonly called a water clock.  Originally developed in 1819.

The english came up with the seconds and minutes thing.\n\nA "minute" is a "minute fraction" (1/60) of an hour. 60 was chosen for being easily divisible into two, three, four, five, and six parts. A "second" is a "second minute fraction" of an hour (1/60*1/60 = 1/3600).\n\nI believe that the romans were the first to use a system of 24 hours. 24 was selected, again, for being easily divisible into two, three, four, and six parts.
