Actually, after further consideration I'm pretty sure the headers I  
saw were correct. If I see a similar phenomenon again I'll raise my  
eyebrows, but I'm pretty sure what we were seeing was a result of

a) using a calendar that hadn't been modified since the day before and
b) the strange "old headers show in firebug" behavior we see with  
this bug
