Tweet timestamps are off by hours

The JSON data that is used for including Twitter data on a website is sending incorrect time information. For a tweet that I made just now, at 1:49 PM EST (-0400) the data is:

"created_at":"Fri Jun 27 12:49:03 +0000 2008"

This is plainly wrong. If it's UTC then I'd expect it to be 5:49 PM.

It should be noted that this incorrect time is *also displayed on the website* leading me to believe there are some funky math problems going on in a more central location.
