convert your date to strtotime and then subtract one hour from it

$now =  date('Y-m-d H:i:s');
$time   = strtotime($now);
$time   = $time - (60*60); //one hour
$beforeOneHour = date("Y-m-d H:i:s", $time);

You could use the date_create function along with the date_sub function like I have shown here below: -

$currentTime = date_create(now());
$modifyTime = date_sub($currentTime,date_interval_create_from_date_string("1 hour"));
$liveTime = $modifyTime->format('Y-m-d H:i:s');

Another way - without all the math and, in my opinion, reads better.

$hour_ago = strtotime('-1 hour');

First convert hours into seconds (3600) then use the following:

$your_date = date('F jS, Y',time() - 3600);

$livetime = time() - 3600; // 3600 seconds in 1 hour : 60 seconds (1 min) * 60 (minutes in hour)

See time PHP function for more information.

Current time is equal to time() (current time given in seconds after Unix epoch).

Thus, to calculate what you need, you need to perform calculation: time() - 60*60 (current time in seconds minus 60 minutes times 60 seconds).

$time_you_need = time() - 60*60;

If you're looking for how to display the time in a human readable format, these examples will help:

$livetime = date('H:i:s', time() - 3600); // 16:00:00
$livetime = date('g:iA ', time() - 3600); // 4:00PM

Assuming that a timestamp is fine you can use the time function like so

<?php
$livetime = time() - 60 * 60;
