Hi.

[quote user=""]When I try to create the sample LWM2M client program it crashes. I do do even get to the point where it loads and I can build it.[/quote]

What errors do you get? Which NCS version? What board are you trying to build for? Did you select the non-secure version?

[quote user=""]I am trying to get the current time and the current time zone.[/quote]

[quote user=""]is LWM2M the right tool to use and if so how do I use it?[/quote]

I am not very experienced with LwM2M myself yet, but there does seem to be objects that can be used to provide the time and timezone.

[quote user=""]Are there any examples that show how to get the current time and time zone[/quote]

No official ones, no.

One of my collegues created an SNTP sample, but it has not been updated in a long time: https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/ntp

Instead, I recommend you take a look at the date_time library on the master branch: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/include/date_time.html

It will use periodic NTP queries to get the time, but it can also be configured to get the (network) time from the modem using AT commands: https://infocenter.nordicsemi.com/topic/ref_at_commands/REF/at_commands/mob_termination_ctrl_status/cclk.html

Best regards,
