DateTime Prob

Hello Guys, I Have Prob

        $now = new DateTime('now');
        $now->setTimezone(new DateTimeZone('Asia/Karachi'));
        echo $now->format('c');

PHP:

This code show me date something like this 2015-08-04T03:49:25+05:00, Thats Correct, But actually I need timestamp, with Asia/Karachi timezone, So when I change echo $now->format('c'); to echo $now->getTimestamp(); output is 1438642165, But when I convert this timestamp to readable time, I got this 2015-08-03T22:49:25+00:00, which is incorrect, please help me to get correct timestamp
Sorry for bad English

 

You are probably converting that timestamp incorrectly or without reference to the timezone you have:

$now = new DateTime('now');
$now->setTimezone(new DateTimeZone('Asia/Karachi'));
echo $now->format('c').PHP_EOL;

$time = $now->getTimestamp();
echo $time.PHP_EOL;

$now = new DateTime();
$now->setTimestamp($time);
echo $now->format('c').PHP_EOL;

/*
2015-08-04T05:01:48+05:00
1438646508
2015-08-03T17:01:48-07:00
*/

Code (markup):

You need to insure that the timezone is set before you output the time like so:

$now = new DateTime('now');
$now->setTimezone(new DateTimeZone('Asia/Karachi'));
echo $now->format('c').PHP_EOL;

$time = $now->getTimestamp();
echo $time.PHP_EOL;

$now = new DateTime();
$now->setTimezone(new DateTimeZone('Asia/Karachi'));
$now->setTimestamp($time);
echo $now->format('c').PHP_EOL;

/*
2015-08-04T04:58:28+05:00
1438646308
2015-08-04T04:58:28+05:00
*/

Code (markup):

You can see that the timestamp you have reflects the timezone you have set.

 

If I get timestamp from db, then should I set the timezone again ?

 

Yes, you will have to to get the correct time you want.
