Publish (and draft) date and time wrong

I’m using WordPress 3.2.1 on my own server (CentOS 6 64bit, PHP 5.2.17).

Link to my website: https://www.tweaking4all.com (I manually corrected date and time in the admin pages so they would show up correctly)

When saving a post as a draft, it saves it with the wrong date (Jan 25 instead of July 26 – year is correct) and wrong time (always 0:00). Obviously when publishing a post the date and time is equally wrong, which I tend have to correct manually after posting (since I can’t edit the date/time of a draft).

– Server date/time is correct it seems: Tue Jul 26 22:45:47 EDT 2011

– Time settings in admin page (Tools>General) is set to Chicago, showing
“UTC time is 2011-07-27 2:45:53”
“Local time is 2011-07-26 21:45:53” (daylight saving)

– Examples (for Date format) in the admin page display correct as well (July 26, 2011, 9:45PM)

I hope someone can help me – I must be overlooking something very simple.
