As everybody trys to "figure it out" the big variable that goes unmentioned is the contrast between the countdown timer, call it actual real time if you wish, and the time stamp applied by CC mailbox. Is it Gmail webmail he uses, is it a client, such as Outlook or Outlook Express and no matter what it really is, how does it correlate to the "real time" of the countdown timer. There could be different by seconds. There source is not the same hence there is no direct relationship.
Just a few thoughts, not bitterness (I did ok), just throwing it out there.
