Help with Calendar Widgets

[Sailrace]

So here's my problem. I've had my Hero for about 20 days. For the most part, i'm loving it (aside from the dust behind the screen). I've discovered a bug that is absolutely killing me, and i don't know how to fix it.

On my home screen, i have the Sense flip clock and the HTC Calendar Widget that is one line tall and the width of the screen. For some reason, this calendar widget cannot seem to get notification and dates right. It drives me crazy when i'm looking quickly to see what's on my calendar. As an example, today, it says December 30 (as it should) and then says "Tomorrow: All Day, New Years Day", which is clearly wrong. i tried switching to the Android Calendar widget, and woke my phone up this morning to discover that it still said it was Tuesday the 29th. So i don't know what on earth is going on.

I'm running Fresh 1.0 (de-freshed) and am desperately looking for a solution. I may flash back to stock to see if that fixes anything. Anyone else seen anything like this?
