If sunset time is stated in hours and minutes, then minutes are what you validate, not minutes and seconds? I guess there is a lot more to this story we are not told.

Exactly my opinion, too.

You can legally fly a glider after sunset IF it is equipped with navigational lights. A friend of mine did exactly that. So, unless you KNOW the glider DIDN'T have nav lights, you can't say DEFINITIVELY that the flight was illegal.
