In 3D sailing, whenever the hour changes, so does the day. The time goes straight from Wednesday 10th 10:59 to Thursday 11th 11:00.
I have both an older version of Beta 3.5 and an installation of Beta 3.4, as well as the up to date version of Beta 3.5 in which I've been doing my work on "Hornblower". Both versions of Beta 3.5 do this, and it's not limited to "Hornblower" because as a test I started the older Beta 3.5 with a new game of "Nelson's First Command" and saw the same problem. I've no idea how up to date that version of Beta 3.5 is, though the fact that I started "Nelson's First Command" and not a generic free-play may be a clue. Beta 3.4 did not show the problem, so it's something which has been done to Beta 3.5.
