As reported here by some members, the timestamps of posts were out by 24 minutes for some of today, but it looks like it might be fixed now. (let me know if it is still happening for you)

It looks like a fault on the part of the Server host, as the messageboard database uses their clock as the default setting, and your personal user settings then adjust ALL times on your screen (and your post times) equally.

It now looks to be back to the proper time... but it has meant that a period of 24 minutes of posts were shuffled in behind earlier posts (due to the time stamping).

Keep an eye out, and let me know if it happens again.
