I'm writing to advise all members to hop over to their user profile on IxDA.org, click 'Edit', and scroll all the way down to 'Locale Settings' to verify that their time zone is set correctly.
If you haven't disturbed that part of your profile, there is a chance the time zone is mysteriously set to something that it shouldn't be. Several IxDA Pittsburgh members had this curious issue (it was set to Chicago), and it causes upcoming events to be shown with the wrong time of day, from your perspective.
It's befuddling. We suspect the time zone setting operates separately from the basic 'location' listed on the public face of your profile. (Ours were all 'Pittsburgh'... thus the stealthiness of the time zone problem.) At the very least, our friends in Lansing may have had the problem (http://www.ixda.org/node/27421) and perhaps you have, too! None of us had intentionally set ours wrong, so -- it's worth a check.
Back to regularly scheduled programming. (Unless somebody else has further insight!)
