PHP时间不准确

When run the code below the result is 12:16:35 am when in realty it is 12:31. does anyone know how to fix this?

Code:

        <?php
           date_default_timezone_set('Europe/Amsterdam');
           echo date("h:i:sa");
        ?>

If it doesn't show your timezone echo date_default_timezone_get();

Then try setting your timezone using

<?php 
date_default_timezone_set('America/Costa_Rica');
echo date("h:i:sa");
?>

you can find the string identifier which suits you best on the link below. http://php.net/manual/en/timezones.america.php
