put in the correct start date and time, but accidentally select a couple of days later as the end date? I think that is what happened on the BYU site. I have their BYU MVB schdule calendar imported in my Google Calendar and that is exactly how it shows up. The website just doesn't do a very good job of making it clear that that is the issue. And no one has gotten around to fixing it.
It says BYU vs UCSB:
Starts: 8pm MT Apr 24
Ends: 10pm MT Apr 26
In fact look at the time details on this page
