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 12s. When compared to the chronometer, the comparing watch reads 08h 01m 22s, and the chronometer reads 07h 59m 39s. What is the chronometer error?

Correct Answer: Option C — 1m 31s slow
Chronometer error is determined by comparing the chronometer time to the known signal time. With the comparing watch at 08:01:22 and chronometer at 07:59:39, the chronometer is 1m 31s slow relative to the signal. This verification is a fundamental requirement for ensuring accuracy in celestial navigation.
