Does Oura Account for Time Zone Changes?
Oura recognizes time zone changes via your phone or device when a Bluetooth connection is established. To ensure your ring is updated to the local time zone, sync your ring with the app before going to bed and check that your phone's operating system is up to date.
If your trip to another time zone is a short one, you can always choose to place your ring on Airplane Mode. Enabling Airplane Mode will allow you to postpone syncing your ring to the app until you return to your original time zone. Your ring will continue to collect data after you’ve enabled Airplane Mode and can do so for up to 6 weeks without syncing to the Oura app.
