Calendar Event not showing for 1/31/2012

We have a calendar entry from 6pm to 9pm on the 31 of Jan 2012 that will not show up on the calendar, but will show in the list of events. 
I can create a new calendar entry for earlier in the day and it will show up, but not if it is from 6pm to 9pm. 
I have also noticed in the "Upcoming events" box on  the Dashboard, an event from the day before is still showing up and should not be.
I have checked the Time Zone on my site and it is set correctly for Anchorage time.
Anybody else seeing this and do they have a fix?
