title: How to convert time string in milliseconds to DateTime object in c#?
body: <p>I have the time in milliseconds as a string like this: <code>229935440730121</code>
  How to convert this string to a <code>DateTime</code> object.
  <br>Thanks</p>
  
  <h2>Update</h2>
  
  <p>Sorry, The correct string is : <code>1423509923000</code> and should be 2/9/15 7:25:23 PM after conversion. It's a time string received from an telemetry device.</p>
