title: add minutes to timestamp- most efficient way
body: <p>I have to write a java code to add minutes(delayminutes) to a timestamp(tmpTimeStamp). This is what I have. I was wondering if this is an efficient way to do this or if there is a better way.</p>
  
  <pre><code>long t=tmpTimeStamp.getTime();
  long m=delayMinutes*60*1000;
  targetDeliveryStamp= new Timestamp(t+m);
  </code></pre>
