I tracked down the feed in the database, and it seems like Nimbus (the back-end for Litenin) read the published date correctly. The item was published ahead of time (it's 21:29 UTC time right now): http://feed.dilbert.com/dilbert/daily_strip
Any suggestions on how to handle this in a more graceful way?
You don't see things as extreme as this everyday. Even with the focus of late on simplicity and flatness.
