OK. We are the mods afterall. Plus, I put in 1 hour for the duration of some events, but if you click on, say, the date of the day after the event, it shows the event as still running. Have I misunderstood the 'during' field?
to put the time into the posts automatically check this:
you will have to add the date in the _calendar_box._row._cell.switch_filled._event template assignement in functions_calendar.php, adding the hour ie to the event title. The date/time is available from the $events array.
