When daylight savings time is kept, the time of tide and current calculations must be adjusted. One way of doing this is to _______________.
AI Explanation
The correct answer is A) add one hour to the times listed under the reference stations.
When daylight saving time is in effect, the tidal and current predictions listed in reference tables are based on standard time. To adjust these predictions to daylight saving time, you must add one hour to the listed times. This ensures the tidal and current information corresponds to the correct local time.
The other answer choices are incorrect. Option B is wrong because the reference station times are not automatically adjusted for daylight saving time. Option C is incorrect because adding 15 degrees to the standard meridian would not properly account for the one-hour daylight saving time shift. Option D is wrong because you add one hour to the reference station times, not subtract one hour from subordinate station time differences.
