Magic Earth uses the same time format as your phone. If the selection from your phone settings is not reflected in Magic Earth, this is what you need to do:
On iOS: Enable 24-Hour Time in your phone’s Settings > General > Date & Time and recheck in Magic Earth.
On Android: Choose between ‘Use 24-hour format’ and ‘Use 12-hour format’ in your phone’s Settings > System > Date & time.
Sometimes the change is not shown immediately in Magic Earth, so please try one of the methods below and recheck in Magic Earth:– turn off the ‘Use 24-hour format’ option in your phone settings
– change to 12-hour format, then back to 24-hour format
