In the web-interface you can configure how the Maxwell will get the correct Date and Time settings.
There is no access to any Date/Time server (NTP) in the network, locally or in the cloud. The Date and Time is set manually in the device.
You configure the Date/Time server manually via the web-interface.
This is the default setting.
Use DHCP option 42 for the NTP server setting, when not send then use the NTP server send via provisioning.
