You looked (though not too directly) at the sun. Later you used arrangements of rocks and calculated time by shadows, and later still, sundials became popular. The peasants simply got up at daylight and went to bed when the sun had gone well down, to save on candles. In between they tended crops and cattle at the appropriate time. Crops and cattle tend to let you know if you're getting it wrong; crops wither and cows and pigs and goats and so on wake you up in the night if they're not comfortable. But only a very bad farmer would get it wrong, and didn't need a clock to get it right. Flower clocks were created as a novelty, but still told the time. The first mechanical clocks were a novelty, and for the wealthy, who in any case had servants to take note of when the sun rose.
Before time zones, each city kept its own time, marking noon as the time when the sun reached its zenith as seen from that city (+/- an offset to compensate for the variation in the length of a day).
Many different instruments are used to measure time. It all depends upon the scale of time you are measuring. Clocks, stop watches, chronometers, sundials, and calendars are just a few. if you just say in simple manner it's clock or watch.
Ok they measure time like how we measure time today like they do the same thing we do maybe i guess it
It means that even though we can hold time (like a watch or clock), we can't control it. We can only measure time and there is nothing we can do to change time.
Flip-flop setup time refers to the minimum amount of time that the data input must be stable before the clock edge for the flip-flop to correctly latch the data. Hold time, on the other hand, refers to the minimum amount of time that the data input must be stable after the clock edge for the flip-flop to correctly store the data. In summary, setup time is the minimum time before the clock edge, while hold time is the minimum time after the clock edge for proper operation of the flip-flop.
This depends on what you wish to measure. A Balance or a scale would be used for mass or weight. A ruler for length, or perhaps a vernier caliper. A clock for time. and so on.
You can measure time using a: Sundial Water Clock Sandglass Pendunum Clock Quartz Clock
Time.
it was invented to tell time
you use a clock
Actually the clock was invented by a bunch of people. The ancients created the sundial which was the first instrument to measure time. The guy you're thinking of is Eli Terry, who in 1797 received his first patent for a clock. He is known as the founder of the American clock-making industry. You can find more info on Wikipedia.
A clock?
The ancient civilization that is credited with inventing the clock is the Sumerians. They were thought to have created the clock's hour system with 24 hours and 60 minutes and the first clock prototypes known as sundials.
If the clock was not invented,there would not be a Daylight saving time for Arizona and Hawaii.
father time
the star clock was invented so that people could tell what time it is at night without the use of clocks
In the past, a common time measuring instrument was the sundial. Today, the usual measuring instruments for time are clocks and watches. For highly accurate measurement of time an atomic clock is used. Stop watches are also used to measure time in some sports.
it is a clock that uses sand to measure time
