As mentioned in the title, event begin times are correctly shown in calendar view, but in detailed view, the start time is decremented. The amount of time decremented varies, but I notice that events with identical start/end times result in identical decremental times in the detailed view.
Using WP v3.2.1 + all-in-one-event-calendar v1.0.7
I'd like to add, this plugin exceeded expectation in both aesthetics and functionality. Nice work.
