Loftie pulls your timezone from your internet connection. If you are running a Pihole, a VPN, or other privacy hardware or software, it may be blocking the API we use to determine your timezone. You can whitelist https://ip-api.com/ and your Loftie should be able to accurately determine the correct timezone.
No idea what any of those terms are? Don’t worry, we’ve got you. You can manually change your timezone under Settings.
