Cool. Not all telcos provide the NITZ message - and there is a lot of variation between which NITZ sub messages are provided as well. Note that the time zone (+38 in your case) is the number 15 minute increments difference between the time provided and UTC. In your case you are 9.5 hours (central Australia?) ahead of UTC.

Me too. I’ll keep wracking my brain trying to remember where/how I saw the module automatically update time based on the network connection.

ciao, Dave
