尽管时间戳正确,PHP日期显示错误的时间

I'm having a problem with the PHP date function which I've never had a problem with before.

The timestamp is entirely correct, however for some bizarre reason date() is outputting a time which does not correspond.

I have the following timestamp (and this is definitely the correct one - when I echo it out onto the page, as well as in the database, it shows as being correct):

464400

Yet when I use the following line of code:

<?php echo date("H:i",$timestamp); ?>

I'm getting a time of 4 am? If I paste the timestamp into a timestamp converter website, then it shows the time should in fact be 9am.

I'm completely stuck, this has never happened to me before & this problem has only just come up recently - the code hasn't been changed and everything seemed to be working correctly before.

Does anyone have any experience with this issue? Any help would be appreciated.

That time stamp is is 9am GMT timezone, if you are in another timezone then you will need to adjust it accordingly.

http://php.net/manual/en/function.date-default-timezone-set.php

  date_default_timezone_set('Europe/London');

or even better in your php.ini

http://php.net/manual/en/datetime.configuration.php

date.timezone="Europe/London"

Or you can use more specifically GMT instead of Europe/London (which has DST)

try this

// set default timezone
date_default_timezone_set('UTC');
//define unix timestamp
$timestamp = 1456778973;
// output
echo date('d M Y H:i:s',$timestamp);

Try this converter too http://freeonlinetools24.com/

try this method will work

for time zone http://php.net/manual/en/timezones.php

code

<?php
date_default_timezone_set('Asia/Kolkata'); 

$dt2=date("Y-m-d H:i:s");
echo $dt2;

?>
