BB Bold :: Email Dates Stuck On 2045?

I have a user who told me the date on his blackberry suddenly turned to 2045.(i dont know how it can suddenly change the date by itself but apparently it has)His secetary set the time back to 2012 and correct time but all his emails are now set to 2045. All his new emails are coming in with the correct time stamp, but the anything past a few days shoes 2045.The blackeberry is set up on a Bes server with exchange 2010.I have spoken to blackberry support and the techguys said that nothing can be done to resolve it, and that the only option I have is to wipe the phone, delete the account and set it up again.I have also removed the desktop cmime service from the phone and reinstalled it but it did not make a difference.I just find it bizare that the BB would change the time stamp on the emails when the time changed to 4045 but when I change the time now all the previous emails wont change their timestamp.Any ideas onhow to get the emails to go back to the original time frame they were in with out having to wipe the phone, My user does not want to lose the emails.
