At the moment I find some difficulties in using timers, prescalers without a clear example, but if I have no other options I'd have to. I get the time stamps using strftime but the time goes really fast, the hours behavior is similar to a second in real time, why is it like this? Because that function should return the right time, the only problem I thought I could have was the fact that I haven't set the time, so it could start from 01/01/01 00:00:00 for example. But I didn't expect that the time behavior was so different compared to a real time one.

Your code is ok from a C point of view (compiled with gcc on a mac or linux the result is 2 digit year = 14) , but with nRF51 you need a RTC/CALENDAR. See this about RTC/CALENDAR, sfrtime not works with nRF51822.
