title: Understanding what a particular proc code does
body: <p>I wanted to get an idea as to what what the these two proc blocks do. I am reviewing some code and I came across this.  </p>
  
  <pre><code>PARSE_TIME = Proc.new do |field|
  Time.at(field.to_i / 1000)
  end
  
  RENDER_TIME = Proc.new do |field|
  field.to_i * 1000
  end
  </code></pre>
  
  <p>Thanks!</p>
