Error on Dashboard

I think this began when I attempted, with no knowledge of what the hell I am doing, to edit the timestamp. Even though I returned the timestamp to default, I get this error repeatedly in comments on the dashboard in admin,

Windows does not support dates prior to midnight (00:00:00), January 1, 1970 in c:\wamp\www\taiwantroll.com\wp-includes\template-functions-links.php on line
