strtotime minus hours and minutes

Question

I have this code:

<?php 
    $date = date('Y-m-d H:i:s', strtotime('-6 hours', (int)get_the_time('U'))); 
    echo $date; 
?>

as you can see the time is changed by subtracting 6 hours from the time, what I want to subtract the hours and also minutes so I tried this:

<?php 
    $date = date('Y-m-d H:i:s', strtotime('-6 hours', '-23 minutes', (int)get_the_time('U'))); 
    echo $date; 
?>

But isn't working, any idea?

Thank you in advance

Answer 1

The strtotime function expecting only 2 parameters.

int strtotime ( string $time [, int $now = time() ] )

So you should try the following format:

$date = strtotime('-6 hours, -43 minutes', $time);

Tested Code:

<?php
$time = time();
$date = strtotime('-6 hours', $time);
echo date('d-m-y H:i', $time);
echo date('d-m-y H:i', $date);


$date = strtotime('-6 hours, -43 minutes', $time);
echo date('d-m-y H:i', $time);
echo date('d-m-y H:i', $date);

Output:

19-10-17 00:44
18-10-17 18:44

19-10-17 00:44
18-10-17 18:01

Answer 2

$time=time();
$datetime_from = date("Y-m-d H:i", strtotime("-43 minutes", strtotime("-6 hours",$time)));
