I'm puzzled as to why the date says Feb 2nd when new comments are made.

The site is: http://nadiatahir.com/

Unless you hard coded a date in the Ato->Edit POST/PAGE INFO ITEMS options, then it is some environmental issue at your host.

WordPress uses the system date to build the datestamp when a comment is added and that is the date that is displayed.

It could be that the computer that you are hosted on had it's date set incorrectly to 2/2/2011. I'd check with your host

I have <image(calendar-gray.gif)> %date('M jS, Y')% in the kicker sections.

It's weird though, because the datestamp is accurate when publishing a new post.
I tried to manually edit the date of the comments in the comments panel but they all display Feb 02 regardless.

If you mean the computer I'm at, it's date is set correctly.

I mean the computer that wordpress is running on.

To see if it is theme related, you could switch to twenty ten and add a comment. If it shows with Feb 2, you will know it is not theme related
