I am using chrome browser. It may be different with Firefox.

On xubuntu select "Time and Date" from the menu. Check the time zone. 
Click Unlock and fix it. Relaunch chrome.

I just tested this as follows: I am in the Eastern time zone.

I went to web app and saw in backend status, schedule, a bunch of shows 
scheduled for 8 PM on various days.

I went to "Time and Date" and changed the time zone to America/Los 
Angeles. Closed chrome and opened again. Went to backend status and now 
the shows are scheduled for 5 PM on various days.

The program schedule now lists prime time shows at 5 PM instead of 8 PM.

Does this work for you? Are there specific pages in the web app that 
show the wrong time zone?
