Measurement of Time
Measurement of Time M.Y. ANAND, B.A. KAGALI* Department of Physics, Bangalore University, Bangalore 560056 *email: [email protected] ABSTRACT Time was historically measured using the periodic motions of the sun and stars. Various types of sun clocks were devised in Egypt, Greece and Europe. Different types of water clocks were assembled with ever greater accuracy. Only in the seventeenth century did the mechanical clock with pendulums and springs appeared. Accurate quartz clocks and atomic clocks were developed in the first half of the twentieth century. Now we have clocks that have better than microsecond accuracy. This article gives a brief account of all these topics. Keywords: Sun clocks, Water clocks, Mechanical clocks, Quartz clocks, Atomic clocks, World Time, Indian Standard time We all know intuitively what time is. It can be civilizations relied upon the apparent motion of roughly equated with change or motions.

American Time Radio Controlled/Quartz Clock
American Time Radio Controlled/Quartz Clock OPERATING INSTRUCTIONS: Step 1: Verify hands are exactly at the 12:00 position. If hands have moved during shipping see “Positioning Hands”. Step 2: Move the slide switch on the movement to match your local time zone. A. P – Pacific Time B. M – Mountain Time C. C – Central Time D. E – Eastern Time Step 3: Remove the red pin. Step 4: Insert a fresh “AA” alkaline battery. That’s it! Clock will automatically reset to the correct time, if signal is available in your area. IMPORTANT: Read all instructions before running any clocks!! ABOUT YOUR RADIO CONTROLLED CLOCK: Your radio controlled clock movement is equipped with circuitry and a receiver to pick up a (60 kHz) time signal (WWVB) transmitted by the National Institute of Standards and Technology (NIST) from Fort Collins, Colorado. The time signal is based on a Cesium clock, one of the most accurate timekeeping devices in the world. Your clock will automatically compare the time signal received to the time on the clock. Once your clock sets itself it will continue to automatically synchronize every day (8X). At startup the sweep will fast run one minute and the hour and minute advance 12 hours and stop at 12:00. After the hands stop the clock will try to receive the time signal (3 – 15 minutes) and if the time signal is received the clock will set (4 minutes). If no signal is received after 15 minutes the clock will start running from the 12:00 position and continue to check for the signal an hour later.

Time Keeping with Quartz Crystals
TIME KEEPING WITH QUARTZ CRYSTALS “The only reason for time is so that everything doesn't happen at once” said Albert Einstein (Fig. 1). One can only assume he wasn’t talking about synchronised global networks when he made this comment. Figure 1 Time is more important than oscillator frequency if events must happen synchronously. The frequency and accuracy of the oscillators generating the ‘timing’ is not critical so long as they all know exactly what time it is. If, on the other hand, the oscillator generating the timing cannot synchronise itself to a reference timing source then the accuracy of the oscillators frequency generating the time is now vitally important. The internationally recognised time standard is UTC (Coordinated Universal Time) and is maintained by the National Institute of Standards and Technology, a branch of the United States Department of Commerce. In Telecoms infrastructure the various levels of required timing accuracies are defined as Stratum levels 1 to 4. The most accurate, and hence the Primary Reference Source is Stratum 1, an atomic clock (usually a Caesium Beam or Hydrogen Maser) which maintains its frequency to an accuracy of <1x10-11 for life. The next level, Stratum 2, maintains its frequency to an accuracy of <1x10-10 per day with Stratum 3 maintaining its frequency to an accuracy of <3.7x10-7 per day. Stratum level 2 is implemented with a precision OCXO (Oven Controlled Crystal Oscillator) using a SC cut crystal. Stratum level 3 is implemented with a precision TCXO (Temperature Compensated Crystal Oscillator) using an AT cut crystal.

Allset® Series Electric Clocks Metal Case
AllSet® Series Electric Clocks Metal Case FEATURES • 3 Year Warranty • Automatically adjusts for Daylight Saving Time changes • No signals or antennas required • 120vac • Heavy-duty all metal bezel • Durable powder coat finish GENERAL The American Time® AllSet electric clocks, with automatic DST feature, are ideal for schools, hospitals, and state and federal buildings. Clock bezel is constructed of durable, 21 gauge cold rolled steel, manufactured to specific high quality standards, with a durable powder coat finish. Glass crystal is highly resistant to scratches. Shatter-resistant plexiglass crystals are also available (standard on 15" clocks). Customization of dials is available. The hour and minute hands are black aluminum. Sweep second hand is red aluminum. DESCRIPTION The AllSet quartz clock movement features a microchip with an internal alkaline battery that keeps track of the current date and time. The microchip is programmed to make the daylight saving time changes at 03:00 a.m. Eastern, 02:00 a.m. Central, 01:00 a.m. Mountain and 12:00 a.m. Pacific time twice a year. In the fall, the movement will stop moving the hands for one hour and start ticking again when the clock is on time to adjust from daylight saving time to standard time. In the spring, the movement will advance the hands forward one hour, at an accelerated speed, to achieve the correct daylight saving time. Clocks use a quartz-based electric movement which operates from 120vac for years of maintenance-free operation. Note: Time must be manually set at startup and after power outages. Internal time/date is only used for moving hands for DST changes.

Quartz Clocks of the Greenwich Time Service
QUARTZ CLOCKS OF THE GREENWICH TIME SERVICE Humphry M. Smith (Communicated by the Astronomer Royal) (Received 1952 November 13) 1953MNRAS.113...67S Summary A general account is given of the development of the quartz clocks of the Greenwich Time Service, and the present installation is described. The methods by which clock performance may be studied are described and a convenient criterion is proposed. Quantitative results are presented in tabular form. The degree of stability now attained represents a significant advance upon that of some five years ago. Details are given of development work now in progress with a view to improving stability still further. 1. General description.-The first quartz clock of the Observatory was installed at Greenwich in 1939, and was of the pattern developed at the National Physical Laboratory ( I) . This employed a ring crystal supported. on phosphor-bronze pins and mounted in an evacuated glass vessel held at a constant temperature by means of a mercury thermometer. The crystal was· incorporated in a simple Pierce oscillator circuit, and was designed to .oscillate at 99'3 kc/s. The divider chain performed successive division by 3, 6 and II, giving an output of 500 cycles per sidereal second to drive a phonic motor. This clock, Q3, took its place among the standard pendulum clocks of the Time Service, which were also supplemented by data received daily from the National Physical Laboratory regarding two similar quartz clocks Q2 and Q6. Clocks employing G T-cut plate crystals in a drive circuit based upon the Meacham bridge (2) were developed independently at the Post Office Radio Branch Laboratories.

Atomic Time-Keeping from 1955 to the Present

We consider a consequence of the accuracy of time measurement, i.e. the entry of Einstein’s general relativity into metrology and its applications. We give some details about the method of calculation and the characteristics of International Atomic Time, and we show how it is disseminated at the ultimate level of precision. 1. Introduction The goal of astronomers was to produce a time scale for worldwide use which was the best possible representation After the construction of the ﬁrst operational caesium of absolute Newtonian time. The lack of uniformity of the frequency standard at the National Physical Laboratory (UK) realized time is characterized by an estimation of relative in 1955, it was quickly recognized that the selected transition variations of rate, denoted by u, over speciﬁed intervals. was the best choice and could serve as a reference for Another important characteristic is the smallest uncertainty frequencies, as the angstrom had served for wavelength in ε in assigning a date to an event.
