title: Converting into date-time format in pandas?
body: <p>I need help converting into python/pandas date time format. For example, my times are saved like the following line:</p>
  
  <pre><code>2017-01-01 05:30:24.468911+00:00
  .....
  2017-05-05 01:51:31.351718+00:00
  </code></pre>
  
  <p>and I want to know the simplest way to convert this into date time format for essentially performing operations with time (like what is the range in days of my dataset to split up my dataset into chunks by time, what's the time difference from one time to another)? I don't mind losing some of the significance for the times if that makes things easier. Thank you so much!</p>
