The time on my Kello is wrong
Kello is getting the time through a Network Time Protocole server that's extremely precise. However, for technical reasons, every time you connect to Kello with your phone, Kello will display the time used by your phone.
So if your phone isn't displaying the right time, check its settings.
Kello's timezone is always the same as your phone's.
If your Kello is displaying a time that is a few hours off, it's probably because your phone is on the wrong timezone. So change your timezone in your phone's settings, then launch the Kello app and wait for it to connect to Kello.
