Why UniversalTime in game and in maneuver node editor are different.

[serg.bloim]

I placed a maneuver node on my orbit and then noticed that the node's time shown in the node editor is in the past. It shows 11d, 03:50:30. But it is already 12d(shown in the top time box near to the warp indicator). It turns out the difference is exactly 1 day.

I checked a couple of times with freshly created nodes and the behavior is consistent.

On the screenshot I caught a moment when the ship is on the maneuver node, so you can compare times. It is not a huge issue and possible to work around. I basically wanted to check, do others have this bug? Is it a known issue? And please let me know if you know how to make these values aligned.

Yes, the off-by-one bug in the days and years has been there since the manoeuvre editor was introduced.

I believe the UT counter is counting up from the start time with a zero index, but the calendar is date-based and starts on the first day of the first year (what's the 0th day of a month?) so T + 0 years, 0 days, 0 hours, 0 minutes and 1 second is the same as Y1, D1, 00:00:01.
