Add hours to timestamp without converting to unix? - php

Question

I need to add +7 hours to a timestamp I'm getting from the DB, but I can't change it to unix because I'm using a function to convert it to "2 hours ago" and stuff like that.
How would I go about doing this? Every question I've seen uses strtotime() which doesn't work with the function I'm using.
Here's the function:
function time_passed($datetime, $full = false) {
$datetimes = $datetime;
$now = new DateTime;
$ago = new DateTime($datetimes);
$diff = $now->diff($ago);
$diff->w = floor($diff->d / 7);
$diff->d -= $diff->w * 7;
$string = array(
'y' => 'year',
'm' => 'month',
'w' => 'week',
'd' => 'day',
'h' => 'hour',
'i' => 'minute',
's' => 'second',
);
foreach ($string as $k => &$v) {
if ($diff->$k) {
$v = $diff->$k . ' ' . $v . ($diff->$k > 1 ? 's' : '');
} else {
unset($string[$k]);
}
}
if (!$full) $string = array_slice($string, 0, 1);
return $string ? implode(', ', $string) . ' ago' : 'just now';
}
So I go through this function with for example 2014-09-11 05:14:12 and it outputs 12 hours ago - Although I want it to output 19 hours ago

Answer 1

Why are you trying to add +7 hours? Looks like you are trying to substitute for time zone difference. Why not just declare your $now variable with the timezone setting and let php do the magic for you? new DateTime("now", new DateTimeZone("America/Los_Angeles")); or whatever your timezone is. You can find a list of timezones at http://php.net/timezones
