title: How to read this binary conversion to integer?
body: <p>I'm embarrassed to admits this but I have no idea how to read this. Please see the image. Though I know there is a million library's out there that would zip and unzip a file for me I want to learn and understand how to do this myself. So  my question is simple how do i convert the date in this image. under file modification time. it has <code>0x7d1c</code> how do they get <code>hour 15 minute 40 and second 56</code>. I'm hopelessly trying to understand but I don't understand how to convert. <img src="https://i.stack.imgur.com/7Lcox.png" alt="enter image description here"></p>
  
  <p>This is taken from <a href="https://users.cs.jmu.edu/buchhofp/forensics/formats/pkzip-printable.html" rel="nofollow noreferrer">this</a> site which is trying to explain the zip file format.</p>
  
  <p>Sorry for the dumb question but I'm just at a lost.</p>
  
  <p>Thanks in advance.</p>
