Date added in Mailchimp 12/31/69

Hi,

when ordering a item and having the system add to mailchimp, it will add it in with a date of 12/31/69.

Here is the scenario.
1) if i order and checkout as a guest (not creating a online account during checkout), then it sends the customer information to Mailchimp correctly.

2) If i order and at checkout i “create” a user account, then when it sends the customer info to mailchimp it has a “Date Added” of 12/31/69.

I am enclosing some debug information of the scenarios.
if you want the complete debug, please ask for it.
