New Comment:
After a few hundred lines of flawless code, whenever using the method POST (not GET) the function
error_get_last() catches the following, despite of setting the timezone in the first line of the
code with date_default_timezone_set('Europe/Lisbon');
Array
(
[type] => 2
[message] => Unknown: It is not safe to rely on the system's timezone settings. You are
*required* to use the date.timezone setting or the date_default_timezone_set() function. In case you
used any of those methods and you are still getting this warning, you most likely misspelled the
timezone identifier. We selected 'Europe/London' for '1.0/DST' instead
[file] => Unknown
[line] => 0
)
Curiously, at the end of the script, after printing the array above, printing
date_default_timezone_get() gets me 'Europe/Lisbon', as set in the first line.

Switching "OS" field to "All", this is OS-independent.

Description:
------------
The DateTime constructor throws an Exception warning that it is not safe to rely
on the system's timezone settings if you try to construct a DateTime object and
haven't somehow specified a timezone, whether by using date_default_timezone_set,
the date.timezone setting, or the $timezone argument of DateTime itself.
However, there is another way to specify the timezone for a DateTime object, by
passing a time string which includes a timezone as the first argument to the
constructor. When such a string is given, the $timezone argument is ignored and
the timezone given in the string is always used.
However, this doesn't prevent the Exception from being thrown, even though a
timezone is being specified. To avoid the Exception, you have to have a default
timezone set, or you have to pass a DateTimeZone as the second argument, even
though neither would actually be used for creating the object.
Test script:
---------------
<?php
ini_set('date.timezone', NULL);
try {
$date = new DateTime('2011-08-28T00:00:00+0000');
echo $date->format('O');
} catch (Exception $e) {
echo 'Exception thrown.';
}
echo PHP_EOL;
date_default_timezone_set('America/New_York');
try {
$date = new DateTime('2011-08-28T00:00:00+0000');
echo $date->format('O');
} catch (Exception $e) {
echo 'Exception thrown.';
}
Expected result:
----------------
+0000
+0000
Actual result:
--------------
Exception thrown.
+0000
