Problem with posting order in threads

[ProjectDIBS]

Hello all,

I'm experiencing a new problem with my bulletin board today for the first time. I now have two instances of this problem. What is happening is that a user is posting and it is posting with a date of "yesterday".

In the second case it did "yesterday" and what appears to be an opposite time and it also did today and an opposite time. For example if they posted today at 10:29AM, the post is showing up as Yesterday at 10:29PM.

Here is one of the examples of this problem, just wrong "yesterday":

Here is the example of this problem with the date and time switching:

You can see it went from "Yesterday, 07:49AM", to "Yesterday, 10:49PM", to "Yesterday, 10:52PM" to "Today, 12:06AM"

When in fact everything was posted "Today" at 07:49AM, Today at 10:49AM, Today at 10:52AM and Today at 12:06PM.

Two questions:

1. Why is this happening and how do I stop/prevent it?

2. What can I do to fix the threads (I don't want to delete the posts, just change the date and time)?

FYI...I switched the forum Date/Time options to remove the "Today" and "Yesterday" and actually show the date the forum thinks it was posted (which is still wrong, especially in the second example)
