尽管时间戳正确，PHP日期显示错误的时间

Question

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.

Answer 1

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)
