You are taking a time tick using the 2000 signal from Kekaha-Kauai, Hawaii (WWVH). You hear a series of 1 second dashes followed by a 9 second silent period, then a long 1.3 second dash. At the beginning of the long dash, your comparing watch reads 08h 00m 08s. When compared to the chronometer, the comparing watch reads 08h 01m 15s, and the chronometer reads 07h 59m 55s. What is the chronometer error?

Question

Accepted Answer

Option B: 1m 12s slow. Chronometer error is determined by comparing the chronometer reading to the known time signal. The watch reads 08:00:08 at the signal, while the chronometer reads 07:59:55. The chronometer is 13 seconds slow relative to the watch. Since the watch is 1 minute 05 seconds slow relative to the chronometer, the total error is 1m 12s slow.
