title: Pause execution until specific time in C
body: <p>New programmer here. Like super new. I'm trying to write a program for my dad's birthday. </p>
  
  <pre><code>#include &lt;stdio.h&gt;
  #include &lt;time.h&gt;
  
  int main()
  {
      int CurrentTime;
      system("start https://www.youtube.com/watch?v=FchMuPQOBwA");
      return 0;
  }
  </code></pre>
  
  <p>So far I have that. How do I do it so he is not able to open it before his birthday or specific time? Looked around in time.h and googled a bit but I can't seem to find a solution. Also how do I send it to him so it's just a .exe and he can't see the code? </p>
  
  <p>Thanks in advance</p>
