If you are attending a conference in person it's strongly recommended that you set your timezone to the conference location's timezone as that will make the website show times as they will be when at the conference locale.

The problem was that they chose a timezone that did not adjust for daylight savings time. We highly recommend picking a timezone based on a nearby city, especially if your area observes daylight savings time. Timezones are political and complex and thus confusing. Please check your timezone, and preferably choose a zone based on a city. Note that we are currently in Daylight Savings Time rather than Standard time in most, but not all of the US and Europe.
