Php Convert time in gmt format

问题

I have this string 2012-06-27 16:17:06 and I want to convert it to GMT format.
How can I do that?

Thanks a lot.

回答1:

PHP's DateTime Object is a good choice:

$GMT = new DateTimeZone("GMT");
$date = new DateTime( "2011-01-01 15:00:00", $GMT );
$date->setTimezone( $newTZ );
echo $date->format('Y-m-d H:i:s');

Use gmdate().
Convert your current date format to UNIX timestamp by using strtotime and then use gmdate($format, $timestamp);

Well, strictly speaking you can not do it. If you do not know in what TZ that date has been generated you can not convert it to another TZ.

If that date came from a DB, probably you can query a date with the original TZ.

$date = new DateTime( "2011-01-01 15:00:00", $original_TZ ); 
$date->setTimezone( "GMT" );

// Set timeline
$time_line = time() +7200; // <-- this is timeline +2
$h = gmdate('h', $time_line);
$i = gmdate('i', $time_line);
$s = gmdate('s', $time_line);

$time = $h.":".$i.":".$s;

echo $time;

Try this, It will work

$newTZ = new DateTimeZone("Asia/Calcutta");
date_default_timezone_set("Asia/Calcutta");  
$GMT = new DateTimeZone("GMT");
$date = new DateTime( "2018-09-20 6:00:00 PM", $newTZ );
$date->setTimezone($GMT);
echo $date->format('Y-m-d H:i:s');

Try this.

$time = '2012-06-27 16:17:06';
echo date("l, F j, Y, g:i a",strtotime($time) ); // assuming gmt format
