Sunset time is only calculated to the nearest minute, because the

available to the pilot pre-flight, for a day, or a table for a whole
year, so there is no need for a fudge factor.

Here is the link to the USNO page for determining sunset:

Sunset is also available in-flight from sources already used by the most
cross-country pilots, such as flight software like SeeYou Mobile, and
Garmin hand-held GPS units. I believe a radio call to a flight service
station can also get you the sunset time, but I haven't tried it.
