Answer 1

You don't want the hours, you want the time. And MySQL has a convenient function for that:

select time(datetimecol)

If you want to format the column as a string, then you would just do:

select date_format(datetimecol, '%H:%i%s')

Answer 2

2 ways to solve this.

1st from your query, use:

$query = $pdo->prepare("SELECT time(datetimecol) as thetime FROM timer"); 
$query->execute();

you get exact thetime is time

2nd, use full format datetime and convert it to time only in php

$return = 30 Jun 2017 03:33:52
$return = date("H:i:s", strtotime($return)); // 03:33:52
