* [Calendars] Fixed an issue on calendars where a long-running event wouldn't display properly on multiple days if it started and ended in a different daylight savings time mode.  For instance, an event that started the day before DST and ran for two weeks would only display on a single day in the calendar.  This affected both manual events and events synced from worklists (e.g. tickets).
