This plugin has been working great for the past month. It seemed to be without trigger that all the events in the calendar jumped back 6 hours (as in they displayed their time as 6 hours prior to when it was originally set). My first thought was the UTC must have defaulted back to zero (since I'm in Minnesota, and the 6 hour difference would make sense). Though WP's UTC was functioning as usual and all other publish dates in WP were displaying as normal.
No plugins were updated around this time, and as far as I can tell nothing out of the norm happened in WP or to the calendar around the time of this occurrence, which took pace at the end of September 2010. Which also rules out any daylight savings time issues.
One other strange thing that occurred along side this issue, is that the include and exclude days got one day ahead. This happened regardless of occurrence to any events that had an include or an exclude date(s).
Anyone have any thoughts? Thank you,
