title: How to convert 'HH:MM' to a particular GMT time on Python?
body: <p>Suppose that you have a variable that stores the following time zone format as string type:</p>
  <pre><code>timezone = '(GMT -5:00)'
  </code></pre>
  <p>Now you have the following times, which were set in <code>GMT -4:00</code> time and as string types:</p>
  <pre><code>time1 = '4:00' #am  (GMT -4:00)
  time2 = '9:00' #am  (GMT -4:00)
  </code></pre>
  <p>How can be used the variable <code>timezone</code> to change the <code>time1</code> and <code>time2</code> values to its corresponding local times? that is:</p>
  <pre><code>time1 = '3:00' #am  (GMT -5:00)
  time2 = '8:00' #am  (GMT -5:00)
  </code></pre>
