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 49s. When compared to the chronometer, the comparing watch reads 08h 01m 33s, and the chronometer reads 08h 00m 56s. What is the chronometer error?

Correct Answer: Option B — 0m 12s fast
Calculate chronometer error by comparing the chronometer reading to the broadcast signal time. With the comparing watch at 08:01:33 and chronometer at 08:00:56, the chronometer is 12 seconds fast relative to the signal. This procedure ensures the navigator has the precise time required for accurate celestial position fixing.
