Convert a GMT TimeStamp to Local Time using PHP

Posted on 2016-11-09

I am doing an API call that gives me a type of timestamp in GMT.   For example, it comes in as 2016-11-09T12:18:15+00:00.

I want to convert this to the time of the server running the PHP program which is a GMT -5 and express it YYYY-MM-DD HH:mm:ss

So for the above time how do I convert 2016-11-09T12:18:15+00:00 to 2016-11-09 07:15:15.

Sorry I wasn't more clear. I don't want to set the time AS my local server time, I want to convert the API read time to my local time.

This API call happens in batch mode, so it reads four hours worth of data so I can't used the current time. I need to convert the time that comes to me as the GMT format into what the equivalent time was when the record was created.

Right - that's strtotime() and date().  The date_default_timezone is your local setting.  It has to be right for the date/time functions of PHP to consider your locale.  You can check it by running this script, shown here in its entirety, and looking for "date.timezone" in the output.
<?php phpinfo();

Open in new window

Then do something like this:
<?php // /demo/temp_pkonstan1.php

$gmt = '2016-11-09T12:18:15+00:00';
$fmt = 'Y-m-d H:i:s';

$loc = date($fmt, strtotime($gmt));

// OOP
$dto = new DateTime($gmt);
$dto->setTimeZone(new DateTimeZone( date_default_timezone_get() ));
$loc = $dto->format($fmt);

Open in new window
