Change timezone

[waddledoo]

How would I change the current timezone used within a php script?

 

The method I usually use, date_default_timezone_set() is undefined on my webhost, so I am trying to find another way.

[joel24]

//change timezone php
putenv('TZ=Australia/Sydney');

 

and to change it in your mysql database

//get offset, including daylight savings because mysql won't
$currentOffset = "+".(date("Z") / 60 / 60).":00";

//timezone mysql
$update_tz = @mysql_query("SET time_zone = '$currentOffset'") or die(mysql_error());

This code:

<?php
date_default_timezone_set('Canada/mountain');  //this is on my computer; on the webhost it is unnecessary
echo date('H:i:s');
putenv('TZ=UTC');
echo "<br>";
echo date ('H:i:s');
?>

 

Is displaying this:

 

20:01:30

20:01:30

 

 

What am I doing wrong?

 

EDIT:

I don't know what the issue is on my own computer, but using the 'putenv' with the webhost works perfectly, thanks!
