Problem with a timed waiting method

[RSemple]

I am using a thingy:91 device. I am basically just attempting to write a method that will just wait for a certain amount of seconds (ie: 10 or longer). This is my code below, however, when it runs, time(NULL) and time(0) return a value of -1, and therefore doesn't really work. Does anyone have any ideas to help me along? I'm not really sure why this isn't working. I have tried to use the date_time.h and the time.h libraries. Just for the record, this builds perfectly in SES.

#include <time.h>
:
void waitFor (unsigned int secs) {
    unsigned int retTime = time(0) + secs;   // Get finishing time.
    while (time(0) < retTime);               // Loop until it arrives.
}

Hi,

Not sure what is wrong here since I am not familiar with the time() library. I instead recommend to use the k_sleep() api, since that will reduce current consumption and also allow other threads to be serviced:

If you are interested in the date time library I could find this case:
