BOWDITCH says this:
1801. Equation of Time
To calculate latitude and
longitude at LAN, the navigator
seldom requires the time
of meridian passage to accuracies
greater than one minute.
Therefore, use the time listed under
the “Mer. Pass.”
column to estimate LAN unless extraordinary
accuracy is required.
