The function for setting the time is nrf_cal_set_time(), and the function for getting the time is nrf_cal_get_time(). The former takes in integers for year, month, day, hour, minute and second, so for that you need to convert from epoch to those values. The latter returns a tm struct from the standard library time.h, which has integer fields tm_sec, tm_min, tm_hour, tm_mday, tm_mon, tm_year, tm_wday, tm_yday and tm_isdst as defined e.g. at <a href="https://www.tutorialspoint.com/c_standard_library/time_h.htm">https://www.tutorialspoint.com/c_standard_library/time_h.htm</a>.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
