title: Get the time and date of git tags
body: <p>I have a project that is using git and have tagged all the releases with a tag.</p>
  
  <pre><code>$ git tag
  v1.0.0
  v1.0.1
  v1.0.2
  v1.0.3
  v1.1.0
  </code></pre>
  
  <p>My goal is to list the releases and release dates in a web interface (tag/commit date = release date). Currently we list all the releases by using <code>git tag</code>.</p>
  
  <p><strong>How can I get the time and date for when the tag was made (or the commit it points to)?</strong></p>
