Adding 1 hour to time variable

Question

I have a time to which I want to add an hour:

$time = \'10:09\';

I\'ve tried:

$time = strtotime(\'+1 hour\');

strtotime(\'+1          


        

Answer 1

Beware of adding 3600!! may be a problem on day change because of unix timestamp format uses moth before day.

e.g. 2012-03-02 23:33:33 would become 2014-01-13 13:00:00 by adding 3600 better use mktime and date functions they can handle this and things like adding 25 hours etc.

Answer 2

try this it is worked for me.

$time="10:09";
$time = date('H:i', strtotime($time.'+1 hour'));
echo $time;

Answer 3

Simple and smart solution:

date("H:i:s", time()+3600);

Answer 4

Worked for me..

$timestamp = strtotime('10:09') + 60*60;

$time = date('H:i', $timestamp);

echo $time;//11:09

Explanation:

strtotime('10:09') creates a numerical timestamp in seconds, something like 1510450372. Simply add or remove the amount of seconds you need and use date() to convert it back into a human readable format.

$timestamp = strtotime('10:09') + 60*60; // 10:09 + 1 hour
$timestamp = strtotime('10:09') + 60*60*2; // 10:09 + 2 hours
$timestamp = strtotime('10:09') - 60*60; // 10:09 - 1 hour

time() also creates a numerical timestamp but for right now. You can use it in the same way.

$timestamp = time() + 60*60; // now + 1 hour
