I helped my boss today with a weird problem. In his calendars on his iOS devices, an extra line would show up, displaying the GMT time of the event. The event was placed correctly in the timeline, but it included the GMT time in the text. Naturally I did the obligatory Google search and found a lot of other users with the same problem, but not any solutions on how to fix it.
After checking all the settings on Google Calendar and checked the time and calendar settings, I couldn’t find anything wrong. But after checking out his iPad settings, I realized that the old IT guy had missed a thing.
