Task Killer/Task Manager apps can cause countdown widgets to freeze. If you have any of them installed, configure them to ignore Final Countdown.
The only thing that can cause dates to jump or seems is if the timezone is changed. Make sure that the two "same" events have the same timezone settings. By default, your phone will set the default time zone for an event.
DST offset is already accounted for in the remaining event time.
