Schedule Post Button Automatically Publishes Post

For some reason once you change the date and the schedule button appears, once you push it instead of scheduling the post it it says “Post published. View post”

Schedule for: 06-Jun 18, 2013 @ 19:04
Click “Schedule”
Post published. View post

My General Settings are:

UTC time is 2013-06-18 0:10:17
Local time is 2013-06-17 19:10:17

Does anyone know a fix for this?

This started to happen after I upgraded to the latest version. I’ve deactivated all of the plugins thinking that may be the issue? Is there a specific file I need to fix or look into? Any help is very appreciated.
