While you may not want to pay your employees for the time they clock in early, you are legally obligated to. If an employee is ready to work and on the floor, they must be paid even if the time was not authorized. The same goes for employees who stay late.

We cannot imagine our life without clock. Clock helps us to manage our lives. We are depending on clock for our routine activities from wake up in the morning to sleep at night. It helps to be everywhere on time such as reaching to work, leaving work, attend meeting , catch up with friends or any social commitments.

The signal acts like a metronome, which the digital circuit follows in time to coordinate its sequence of actions. Digital circuits rely on clock signals to know when and how to execute the functions that are programmed.

Ancient Egypt The oldest known sundial is from Egypt; it dates back to around 1500 BC (19th Dynasty), and was discovered in the Valley of the Kings in 2013. Sundials have their origin in shadow clocks, which were the first devices used for measuring the parts of a day.

Every mechanical clock needs energy to run. Winding your clock actually winds an internal mainspring. When the mainspring slowly unwinds, it puts a series of parts in motion which results in the turning of the gears. Perhaps the most important component inside a mechanical clock is known as the escapement.

The timekeeping element in every modern clock is a harmonic oscillator, a physical object (resonator) that vibrates or oscillates at a particular frequency. This object can be a pendulum, a tuning fork, a quartz crystal, or the vibration of electrons in atoms as they emit microwaves.

Time is the ongoing sequence of events taking place. The past, present and future. The basic unit of time is the second. There are also minutes, hours, days, weeks, months and years.

In the old times a clock was called a clock which keeps time. But when digital clocks came in which showed no needles but only numerals which had to be read, the clock with needles came to be called as analog clock to differentiate it from other types of clocks and watches.

A clock or watch is called “analog” when it has moving hands and (usually) hours marked from 1 to 12 to show you the time. Some have Roman Numerals (I, II, III, etc) instead, or no numbers at all! In other words: not a digital clock. See: Digital Clock or Watch. Clocks – Digital and Analog.

Analog clock shows time passing by moving hands continuously. In contrast, digital clock shows the time numerically. By analog clock you can tell the time between graduations to some extent by the location of the hands because the hands move continuously.

On the analog clock, the time is represented by hands that spin around a dial and point to a location on the dial that represents the approximate time. On a digital clock, a numeric display indicates the exact time. Analog refers to circuits in which quantities such as voltage or current vary at a continuous rate.

Clock displays. There are many types of clocks and watches. The two most common types of displays on clocks are “analog” and “digital” .

Antique Longcase clocks An antique long case clock is apparently the best known of all the antique and old clocks. Longcase clocks are more commonly known in the US as tall case clocks. It is also called grandmother, granddaughter and grandfather clock which can be discerned by the difference in their sizes.

The first mechanical clocks were invented in Europe around the start of the 14th century and were the standard timekeeping device until the pendulum clock was invented in 1656. There were many components that came together over time to give us the modern-day timekeeping pieces of today.

Examine the clock for the marker’s signature or label. Check the face, mechanism and case. Clocks that are labeled or stamped with the name of its maker or a trademark are more desirable than unmarked clocks. If you can’t find a label or a stamp, you’ll need to identify the type of clock yourself.

Using the Maker’s Name or Company Name to Identify an Antique Clock

1. Engraved or printed near the center face of the dial.
2. Engraved or printed around the edge of the dial’s face and may be covered by the bezel.
3. Stamped or engraved on the clock movement’s backplate.
4. A paper label pasted on the back of the clock.

BookishGirls describes how the first mechanical clock was invented by Henry de Vick around 1360 A.D, but it only struck on the hour. The first pendulum clock arrived in the 1600s, paving the way for Christopher Huygens’s long case clock in 1656. It was named a “grandfather clock” afterward.

# 1. Chime and strike clocks marked Smiths Enfield on the dial or Smith-Enfield on the movement date from 1949 or later. # 2. If the clock has a floating balance movement it dates to 1956 or later.
