It’s the same time. Look at the time stamp at the top of the images (15:05 (aka 3:05) and 4:12). Each is from a different time zone and so the game adjusts the time of the raid to reflect the correct time in that time zone. When you get into the time zone that the gym is in, the raid time will change. Either that, or as DD808 said, one phone is set an hour ahead.
