How do I get UTC time with the XBee 3 Cellular LTE Cat M1 / NB-IoT?
I know I can get the network local time with the ATDT command, but has a way to get UTC time been created?
Having a coordinated time between multiple IoT devices in different time zones is critical to our application. I know modules from other manufacturers can report an offset from UTC, so surely it must be possible. I know I could retrieve UTC time from a server, but I would like a more reliable solution.
