Is the time problem related to daylight savings time? EST is GMT-5, EDT is GMT-4. Do we need to pretend we're in one time zone to the east (Atlantic time for me) to correct for daylight time? And does the server need to be set the same way? If the server is converting GMT improperly for itself, and my user profile is also converting improperly, that would account for the apparent 2 hour error.

I just reset my profile to GMT-4, and will be posting this at about 11:52 EDT.
