PHP: Changing UTC time to Pacific (PST/PDT) [duplicate]

Question

I have a Datetime object and get the time with the following:

$today = date('Y-m-d H:i:s', $temp['date']->getTimeStamp());

I would like to be able to convert this into California's current time, but I need to account for PST and PDT for the time offset. It could be -7 or -8 hours depending on the time of the year. How can I dynamically obtain $today for the correct Pacific time?

Answer 1

You can simply use strtotime to change the timezone, like this:

date_default_timezone_set('Etc/GMT'); //Make sure the time is GMT
$today = date('Y-m-d H:i:s');

echo $today."\n";

$today_utc = date('Y-m-d H:i:s', strtotime( $today." GMT+3"));

echo $today_utc."\n";

$today_9 = date('Y-m-d H:i:s', strtotime( $today." GMT-9"));

echo $today_9;

So in your case your code could be:

$today = date('Y-m-d H:i:s', $temp['date']->getTimeStamp());
$today = date('Y-m-d H:i:s', strtotime( $today." GMT-9"));
