W3C Validation error

Hello,

First of all thank you, Tim, for this terrific plugin.

When I run my site through W3C Validation, I receive the following warning for each Tweet that’s displayed in my widget:

“Bad value (Tue Oct 08 14:40:36 +0000 2013) for attribute datetime on element time: The literal did not satisfy the time-datetime format.”

I’m not sure how to go about fixing that. Can you help, please?

Thank you.
