[Plugin: All-in-One Event Calendar] Various issues with dates & times displaying incorrectly

There are a number of funny things that this plugin has started doing on our website the past two weeks. For a month it was working properly but then we started noticing that some events were displaying one hour off on the full calendar view, but not when the event was clicked on directly. Then there were some events that were actually moved a day. And now the sidebar widget is off by one day for every event.

The events that were off by an hour were actually showing on the backend as what was displaying, but that is not how they were originally entered. Everything else was entered correctly but displaying incorrectly.

The administrator first noticed the change when we had our EDT time change. Is this merely a coincidence?

We’re completely up to date with WordPress and the plugin. Any thoughts on what the issues are?
