Double-check the date and time settings on your device:
- iOS: https://support.apple.com/en-us/HT203483
- Android: https://support.google.com/nexus/answer/2841106?hl=en
- Windows: https://support.microsoft.com/en-us/search?query=setting%20timezone%20in%20windows
Verify that the date and time are set to automatically update, and that you have the correct timezone and date/time set.
If this does not correct the problem, verify that you are using the latest version of your device's operating system, and/or reboot your device.
