The code got scrambled when cutting and pasting. Here's the correct
code.
===================
<?php
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n\n";
date_default_timezone_set("Europe/London");
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n\n";
date_default_timezone_set("UTC");
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n";
?>

Description:
------------
Daylight Savings doesn't work with the UTC time zone
It does work if I set the time zone to Europe/London.
Reproduce code:
---------------
<?php
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $tw?php
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n\n";
date_default_timezone_set("Europe/London");
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:o_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n\n";
date_default_timezone_set("Europe/London");
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n\n";
date_default_timezone_set("UTC");
echo date_default_timezone_get() . "\n";
$two_weeks_ago = date("d-M-Y h:i:s T I", time()-1209600);
echo $two_weeks_ago . "\n";
$right_now = date("d-M-Y h:i:s T I", time());
echo $right_now . "\n";
?>
