This is a common problem when the date/time is incorrectly set :-)
Here are instructions to ensure that the time is correctly recorded and displayed:
- Go to your phone/tablet settings
- Choose the Date and Time option (your phone settings may be a little different depending on your device manufacturer)
- Find "automatic date and time" and activate
- Find "automatic time zone" and activate
Whenever the time appears incorrect you should ensure that these options (automatic date and time and time zone) are enabled.
