Re-load Facebook Events

One of the Facebook events is showing the incorrect start date and time on our home page. The Event shows as:

The 11th Annual Elders Hoolie

The Uptown Theater

Starts at: March 17, 2013 1:00 am

If you click the link, the Facebook event shows the correct date and time, March 16th, 2013 8:00pm.

How can I force the widget to update the correct time from Facebook? Is there a way to delete a cache or some other method to tell it to rebuild the event list so that it pulls the correct time from the event? My suspicion is that the event was originally created with the wrong date and then corrected, but the correction never made it through to the plugin from Facebook.
