title: How to add minutes to a date(timestamp) in Oracle?
body: <p>I created the following tables:</p>
  
  <pre><code>create table travel
  (
      code         VARCHAR2(3),
      date         timestamp,
      constraint pk_code_travel primary key(code)
  );
  
  create table extras
  (
      code_extra          VARCHAR2(3),
      code_travel         VARCHAR2(3),
      minutes             NUMBER(3),
      constraint pk_code_extra primary key(code_extra)
  );
  </code></pre>
  
  <p>I inserted the following dates:</p>
  
  <pre><code>insert into travel (code, date)
  values('T01',TO_TIMESTAMP('10/01/2016 15:30','DD/MM/YYYY HH24:MI'));
  insert into travel (code, date)
  values('T02',TO_TIMESTAMP('15/02/2016 17:45','DD/MM/YYYY HH24:MI'));
  insert into travel (code, date)
  values('T03',TO_TIMESTAMP('01/04/2016 22:00','DD/MM/YYYY HH24:MI'));
  
  insert into extras (code_extra, code_travel, minutes)
  values('E01', 'T01', 50); 
  insert into extras (code_extra, minutes)
  values('E02', 'T02', 123); 
  insert into extras (code_extra, minutes)
  values('E03', 'T03', 48); 
  </code></pre>
  
  <p>The question is: how to add the minutes from the table "extras" to the date of "travel" table ?</p>
  
  <p>For example the table "travel" should be:</p>
  
  <blockquote>
    <p>T01', 10/01/2016 15:30 + 50 minutes.</p>
    
    <p>T02', 15/02/2016 17:45 + 123 'minutes.</p>
    
    <p>T03', 01/04/2016 22:00 + 48 minutes.</p>
  </blockquote>
  
  <p>All help will be appreciated.</p>
