How do I get Greenwich Mean Time in PHP?

Question

I have a server which is set to EST, and all records in the database are set to EST. I would like to know how to set it to GMT. I want to offer a time zone option to my user

Answer 1

Here is a list of the time zones with different from GMT, hope this is helpful!

echo '
';
$zones_array = array();        
$timestamp = time();         
# to maintain the original timezone, store before
$default_timezone = date_default_timezone_get();
foreach (timezone_identifiers_list() as $key => $zone) {    
    date_default_timezone_set($zone);
    $zones_array[$key]['zone'] = $zone;
    $zones_array[$key]['diff_from_GMT'] = date('P', $timestamp);
}
# to maintain the original timezone, re-set after
date_default_timezone_set($default_timezone);    
print_r($zones_array);


Thanks!
