I have this error for date() and mktime() with WordPress 2.7.1 . In my case it selected Chicago. Unfortunate my for readers who are in France. I have another MYSQL application with a form fill which nicely dates the POSTS in Paris time. . In other words the server is in the USA but the customers for both apps are in Europe. How can I do a rewrite in .htaccess to stop these messages? They are like horse droppings.
