How to add period to only TIME (02:00:00) in PHP : <p>I want to add a specific period like 2 hours to only time. <br />
BUT only TIME. There will be no date related issue.</p>

<p>Like my time is 02:00:00 <br />
And I want to add 1 hour to this time. <br />
So, the result will be 03:00:00 <br /></p>

<p>Is there any PHP built-in function like strtotime()? <br />
I don't want explode related function for this like explode(":", $time)</p>

<p>Is it possible? Please help someone.</p>
