After update to 0.8.1 column “date of mail” is empty “in the list of all emails”. When I click on the emial and in the details of email there is also empty field. Interface Larry and Clasic. In the setting checking pretty dates, date format, time zone – no change.
Going back to RC 0.7.1 solves the problem.
Apache 2.2/PHP 5.4.4
Problem was SOLVED by setting in php.ini date.timezone
