You can check time and date in the Settings menu under My frame → Set time zone.
If time is date is incorrect, try the following:
Check if you have selected the right time zone. This is done at the same place where you can see the time and date of the frame.
Check if the frame is connected to the internet. The date should update automatically when connected to the internet.
If it does not update after connecting, then reboot the frame. This should refresh the time.
If you are connected to a guest network or a similar network with limited access to the internet, it could be blocking the frame from being able to update the time. Try to connect to another network to see if this resolves the problem.
If the above steps all fail to resolve the issue, get in touch with the place where you bought your frame to replace it.
