While in the middle of writing a post, I accidentally hit a wrong key. It took me to a new screen. I got back to the screen I was on, but when I wrote the post, at the end, it had this:
"This entry was posted on Wednesday, December 31st, 1969 at 4:00 pm and is filed under . You can follow any responses to this entry through the RSS 2.0 feed. You can skip to the end and leave a response. Pinging is currently not allowed. Edit this entry."
How do I fix this so I get rid of this and get the correct date?
