you could do,

if date('H', time()) == 0 
echo date('H:i', time());

It's best to convert the time to seconds then use a math equation to see if it is over 59 mins in seconds. Then you could use an else to display the H or not.

The standard methods of handling date and time values are given in this article.  Se the parts about Time Without Date and Practical Application #3.

With the test data posted here, I think TvMpt has an accurate solution.  But I think my instincts would lead me to keep the hours, even if they are zero.

You do not need to understand the time() command.  The time() command is not the right tool to use.  This article explains the way to do date and time format conversions.

The quality of test data is usually more important than the programming.  You might want to run this to see what output you will get.

<?php // RAY_temp_rgb192.php
error_reporting(E_ALL);
echo '<pre>';

// TEST DATA WITH AN OUTLIER
$arr = array
( '0:00:02'
, '0:50:04'
, '0:04:08'
, '1:20:30'
, '0:00:09'
, '00:00:09'
)
;

// TRY THE REGEX
foreach ($arr as $sourcestring)
{
    echo PHP_EOL;
    echo $sourcestring;
    echo ' => ';
    echo preg_replace('/(^(0:))/m',' ',$sourcestring);
}
