title: Embed the image build time in code
body: <p>We constantly run into issues where we are running different C images on different machines. Since our code is still in production, we keep generating binaries that folks use. Often lot of time is spent in debugging only to learn later that the binaries were incorrect.</p>
  
  <p>I was wondering if there is some mechanism with which I could print the date and time when I had compiled the code then we could use that to ensure that all binaries are the same.</p>
  
  <p>Any idea on how I can do this in C? I want to print the time and date when I built this image along with the version number.</p>
