I use timetable for 24 hour events - get wide in vertical view. As long as the vertical scroll bar is all the way to the left (looking at am) it's fine. As I scroll to the right (towards PM) the time line does not move with the events and is more and more off - around 11pm it's one hour. I tired AM/PM and 24 hours, no difference. There is a 24hour branch that seems to have fixed that, but code is not comparable in Diff.
