I used time.h library - my linux based central sent unix time which was my exact date/time value to the peripheral (nrf51). I don&#39;t have that implementation anymore because it took too much memory and I just erased it. It was standard <a href="http://www.tutorialspoint.com/c_standard_library/time_h.htm">time.h</a> functions usage although.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36107?ContentTypeID=1Thu, 15 Oct 2015 17:03:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:f2fdfdcb-4afd-4fc8-85c8-3a7fd2c4609aAlessandro<p>My question of few days ago might be a good starting point: <a href="https://devzone.nordicsemi.com/question/53893/best-way-to-implement-system-clock-on-nrf51/">devzone.nordicsemi.com/.../</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/36105?ContentTypeID=1Thu, 15 Oct 2015 15:51:48 GMT137ad170-7792-4731-bb38-c0d22fbe4515:58dfb41a-d6a4-489c-98f5-ebae4b2ab8e2Wojtek<p>Please do not underestimate Nordic support - app_timer is quite well described in SDK documentation. Describing your problem more precisely would increase your chance of getting answers.</p> <p>If you want to implement calendar in nrf51, standard C time.h library would probably be helpful, I have been using it for some date/time related things.</p><div style="clear:both;"></div>
