Herb,
That makes sense to me however Bowditch says the 5 second differential is positive--not negative.

Andrew,
You can see the answer to your question by looking at the Mer. Pass. for Apr. 18 in your attachment. As Mer. Pass. is moving towards an earlier hour as the days progress, it must have happened at 00:00:02 in the morning and at 11:59:55 near noon on the 16th.
In a real world scenario, of course, you would consult the preceeding page in the Almanac to make absolutely sure.
