how do I get time and time zone information

[Timothy]

I am trying to get the current time and the current time zone. I see there is some modem commands LWM2M commands that appear to have the capability to do that. 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. is LWM2M the right tool to use and if so how do I use it? Are there any examples that show how to get the current time and time zone.

Hi.

 

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.

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

 

I am trying to get the current time and the current time zone.

 

is LWM2M the right tool to use and if so how do I use it?

 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.

 

Are there any examples that show how to get the current time and time zone

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

yes that worked. I can get the information from the modem. this can be closed. Thank you very much.
