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 1Clock 2
Monday12:00:0510:15:06
Tuesday12:01:1510:14:59
Wednesday11:59:0810:15:18
Thursday12:01:5010:15:07
Friday11:59:1510:14:53
Saturday12:01:3010:15:24
Sunday12:01:1910:15:11
If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer ?


SOLUTION
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.
