How to add minutes to a date(timestamp) in Oracle?
<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>
