I have Eastern Time zone selected and “Auto correct DST?” checked, and the forum time is one hour later than it should be. I started a new thread (Christmas Present from Calhoon) at 3:50 PM and the time displayed for the post was 4:50 PM.
I unchecked the auto-correction and the time was still one hour late. Just for a test, I checked the “Is daylight saving time in effect?” box and the time was two hours late. I unchecked that box and rechecked the auto-correct box and I’m still seeing one hour late.
I did click the “Change my Account Options” button after each change and my computer clock is correct.
