Get UNIX Time with nrf9160

[thomas oggier]

Hello,

I would like to get current UNIX time with my nrf9160.

First I saw that we can ask the current time from the modem using the AT cmd "AT+CCLK?".

This function works, but give me the date and time and not the UNIX time. 

I saw also that another function exist -> int time_modem_get()

But I don't know how to use it.

I've add in my prj.conf  this two lines:

- CONFIG_DATE_TIME=y

- CONFIG_DATE_TIME_MODEM=y

But I can't compile because the functin time_modem_get is not declared in this scope.

 

Someone has an idea how to use it?

Thanks

Hello! 

Try to use the date_time library instead (#include <date_time.h>). The current time can then be acquired using either the modem or NTP. A simple usage example below:

#include <date_time.h>

/*TIME*/
s64_t unix_time_ms;

/*Force the date_time library to get current time */
date_time_update();

/*Read current time and put in container */
err = date_time_now(&unix_time_ms);

/*Print the current time */
printk("Date_time: %i %i\n", (u32_t)(unix_time_ms/1000000), (u32_t)(unix_time_ms%1000000));

If the program doesn't compile, try to add the following line to prj.conf:

CONFIG_LEGACY_TIMEOUT_API=y

Hope this helps!

Best regards,
Carl Richard

Yes top it works fine

Does not work in SDK/Zephyr 1.3.99.

undefined reference to `date_time_update'

Got the same error. Is there another solution to getting the UNIX time in Zephyr? Thanks!
