When replying to (or forwarding) an email, the date from the header of the original email is not completely carried over to the quoted text.

In the attached example it says "Sent: Tuesday, December 2010 4:47 PM" (no day number), but should say: "Sent: Tuesday, December 28, 2010 4:47 PM" (emphasis mine). Any ideas how to fix? (OS is Windows XP SP3)
