Weird error trying to add comment

[mweiner1]

"Comment post not allowed (400)
Why: The comment form failed security verification: <ul class="errorlist"><li>timestamp<ul class="errorlist"><li>Timestamp check failed</li></ul></li></ul>
The comment you tried to post to this view wasn't saved because something tampered with the security information in the comment form. The message above should explain the problem, or you can check the comment documentation for more help.

You're seeing this error because you have DEBUG = True in your Django settings file. Change that to False, and Django will display a standard 400 error page."

I got the above error after clicking "post" on a comment. I was properly logged in and able to perform other functions on the set.

I went back and tried again and it went through. This may not be a big deal (will update here if I see it happening more frequently) but it probably indicates something.
