Yesterday your chronometer read 02h 59m 58s at the 1500 GMT time tick. Today the chronometer reads 03h 00m 02s at the 1500 GMT time tick. What is the chronometer error?

A +3s
B 03h 00m 02s fast
C 02s fast
D -3s
AI Explanation

The correct answer is C) 02s fast. The chronometer error is calculated by comparing the chronometer's time to the known GMT time tick. Yesterday, the chronometer read 02h 59m 58s at the 1500 GMT time tick. Today, the chronometer reads 03h 00m 02s at the 1500 GMT time tick. This means the chronometer is running 02 seconds fast compared to the GMT time. The other options are incorrect because: A) +3s is not the correct error, as the chronometer is 02s fast, not 3s fast. B) 03h 00m 02s fast is the actual time shown on the chronometer, not the error. D) -3s is incorrect, as the chronometer is running fast, not slow.
