@paul-thornton I replied on another thread that I think you responded to that I have this issue with 1.20.0.rc0. I reverted back to my unmodified build of 1.19.0.b4 and the problem disappeared. I found that after machine.reset() the clock still would not sync reliably (or at all) and even sometimes after a hard reset by hitting the reset button.

Hi @gerkez Are you connected to a WiFi network when you try to run this code? You'll need to have the device connected to a network in order to read ntp time. Cheers, Alex
