Use either of the following methods: If the recording time is consistent with the time zone set in Littlelf Smart, but the watermark time is inconsistent with the actual time, modify the time zone in Littlelf Smart. To do so, tap Me in the lower right corner of the app. Tap your profile photo on the page that appears, and then tap Time Zone to select the current time zone. Remove the device, and add it again through QR code net pairing. Littlelf Smart will automatically retrieve the time settings of your mobile phone and synchronize its own time zone settings.
