If you are viewing sessions in Pheedloop, your browser typically auto-detects your timezone and shows sessions times according to your local time.  To check what timezone you are viewing session times for, click the "Account" section on the left navigation and scroll down to the Schedule Timezone section to check or set your timezone. 

You can also click on individual sessions and the timezone you are viewing the schedule with is listed just under the title of the session.  (In the screenshot below that is MDT).

Sessions times published on any PDF or handouts are for MDT (Mountain Daylight Time), which is the local timezone for Utah, USA where the convention is hosted.  To convert to your local timezone, you can use a tool such as https://www.thetimezoneconverter.com/
