osx - Measure time in minutes in C -

I am writing a program that will need to measure time in minutes.

To be precise, wait 10 minutes, execute some code, wait 2 minutes, execute more code and repeat this time 5 times (no one seems to try what I do I am doing this?) And I'm thinking how to break.

Thanks in advance!

Oh, and by the way, I'm on Mac.

  #include & lt; Stdio.h & gt; # Include & lt; Unistd.h & gt; Sleep (600); // sleep 10 minutes sleep (120); // sleep two minutes  

Or if he is not working, he will get sleep, who argues in the form of a mile which I believe. (1 second = 1000)
