This will affect the New Post Numbers and Icons.
it's probably a time difference on the board versus their profile time offset. ( remember we moved from PST to EST )
I have set the Service time offset to be 0
The go to "My Stuff", Edit Preferences, near the bottom you will see this:
Current server time is: 10/12/11 11:45 PM
Choose your time offset in hours: (..,-2,-1,0,1,2,..)
11:45 is the time I copied the info.
Since I am Central Time Zone, I have my offset at -1
then adjust your individual profile offset to be what you prefer.
the two settings are probably fighting each other, where something 'looks' like it's in the future, but really is in the past
