At present I’m seeing departure/arrival times in CST, GMT and EST.
It appears that the time used is the zone of the departure or arrival airport, however I’m not sure why GMT is sometimes shown. I see a departure at 13:11 GMT with an arrival at 07:48 CST.
It would be great to allow (perhaps through the user’s profile) an option to force the times to be displayed in any zone (including GMT)
Keep up the great work !
