Bug

What's the current behavior?

In the day view of Big Calendar, the events sometimes appear in incorrect positions due to incorrect top and height css values. This does not happen in events with times ending with 00 minutes (eg. 12:00, 17:00), but it happens when the events have odd times like ending on 12:29.
