Where did you find the function date_time_set_timestamp() ?

Did you test the nrf-calendar example? In the nrf-calender example the current time is set with the function nrf_cal_set_time(), nrf_cal_set_time(year, month, day, hour, minute, second);

How can I set the current PC time into: void date_time_set_timestamp(uint32_t timestamp) { uint32_t RTC2_counter;

RTC2_counter = NRF_RTC2->COUNTER;
if(timestamp < (RTC2_counter / 8))
{
    date_time_clock_timestamp = 0;
}
else
{
    date_time_clock_timestamp = timestamp - (RTC2_counter / 8);
}

}

Thanks, it's building the logic that I do not understand. I must keep track of the hours in a day.

Well, I think what Sigurd was trying to say in not so many words is that the RTC peripheral you see on the nRF52 is a real time counter, not a real time clock/calendar. You can use it to keep track of ticks at almost any interval you want, but you have to build the logic on top of it if you want to use it as a clock/calendar. The example he is pointing you to is a way to do that.

I desperately need assistance in being able to set the time and read(get) the time as per above. Any help would be greatly appreciated.

Hi,

For keeping track of time on the nRF52, I would recommend taking a look at the nrf-calendar-example we have on Github.
