What happens when I travel to different time zones, or when my phone changes time?

The app will display a clock icon on the glucose graph to indicate when there has been a time change. It is necessary to use the correct time for accurate reports. If your phone’s time is not set to update automatically, you will need to update your phone’s time settings in order to continue using the app.
