Todays Date is Off on Calendar

Hi, I seem to be having the same problem many other have had with the highlighted, todays, date being a few hours ahead on the calendar view. I turned off configurable timezones as I realized that may have been the problem and despite the fact that my drupal time for posts is now completely accurate, the calendar is still off. Please help me out here and give me some suggestions on how to fix this. Thank you!

BTW, I have Drupal 5.1 with the very latest versions of calendar and date.
