Have you noticed if the dates are incorrect elsewhere and for all users or just one or a few? It might pay to check other forums and the logs.
The date/time is configured for the site via Administration ► Location ► Location settings. If set to 'Server's Local Time' check the time on your server.
Users can also specify their own timezone via the profile settings.
I hope this helps
We were moving a course to a new server, so I backed it up and then restore it on the new machine.
I think this happened at course restore because the course start date defaulted to the current date instead of the backed-up course's original start date and somehow Moodle extrapolated new dates for the forum posts (which I don't think should be proper behavior - forum dates should be the date the posts were created regardless of course start date).
The question now is how/where do I fix this in the database? I still have access to the old site, so I know the "real" dates. I can't just try to restore again because others have posted to the new site since this happened.
Did you ever figure out how to fix this? Exactly the same thing happened to me too.
Exact same thing here....Not only do the forum posts have the wrong date, but when I go to view one I get "Discussion ID was incorrect or no longer exists" As though it did not get backup, although I back up the entire course????
I've had this problem several times over the last year. As no one seems to be offering a solution here I've put it in the tracker: MDL-20756
Thanks for filing this in the tracker. I note you put 1.9.4 on the ticket. FYI we're on 1.9.7, and it is appearing on courses created as duplicates of courses from previous semesters.

is there a temp. fix for it? like changing GMT and date in the DB?
Thanks to Melinda for the tip
If you set the start date of the new course you want to copy to (or restore) to the same start date as the one you want to copy from (or backup) the forum post dates are correct once restored to the new course area.
Sorry it doesn't help if you've already had posts on the new forum, but is a 'fix' if you discover it before
