Its excellent timekeeping qualities are due to the very long and heavy pendulum which allows a small arc of vibration.
Clocks at first were made with only the hour hand; the minute hand was introduced when the use of the pendulum made timekeeping sufficiently accurate for the indication of such small divisions.
The balance was thus never free from the train and goodtimekeeping was made impossible.
Altogether, then, these early clocks were easily surpassed in accuracy of timekeeping by a sun-dial or a good clepsydra.
The work of producing a satisfactory timekeeping machine, begun by priests and by astronomers, and carried forward by the demands of the navigator and the patient labor of the craftsman, had ended after thousands of years, in triumph.
But there is one thing in our modern timekeeping which we still have in common with the first men who ever kept the time.
For real timekeeping there were dials everywhere, and there were also fairly good clocks in the towers; at night, watchmen patrolled the streets and called out the hours.
It had a striking part, and a timekeeping part, each distinct from the other.
This oversight often prevents what would otherwise be excellent results in timekeeping and makes it necessary to utilize extra time and labor in the effort to obtain more consistent timekeeping.
The application of electricity for winding, driving, or regulating clocks is not fundamental, for the timekeeping is done by the master clock with its pendulum and wheels, just as by any grandfather's clock 200 years old.
This wonderful timekeepingis done with seconds pendulums of about 39 in.
The timekeeping of both these watches is remarkably good, and shows that we have entered upon a new era in the manufacture of pocket chronometers; for these rates are better than the majority of marine chronometers.
The cost of these watches, compared with others of similar construction and finish, was excessive; and while they show good timekeeping qualities, they do not equal that of other exhibits.
The timekeeping tests were made, as the report points out, by Prof.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "timekeeping" in a variety of sentences. We hope that you will now be able to make sentences using this word. Other words: chronological; dated; metronomic; temporal; timekeeping; timing
