Question

Two clocks are being tested against a standard clock located in a national laboratory. At 12:00:00 noon bv the standard clock, the readings of the two clocks are :

	Clock 1	Clock 2
Monday	12:00:05	10:15:06
Tuesday	12:01:15	10:14:59
Wednesday	11:59:08	10:15:18
Thursday	12:01:50	10:15:07
Friday	11:59:15	10:14:53
Saturday	12:01:30	10:15:24
Sunday	12:01:19	10:15:11

If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer ?

Answer 1

though the first measurements are more accurate with the real time ,the second measurements are more close to each other ,so the measure, time intervals precision is required.In clock 2 precision is more so we need to use clock 2.
