Bug description:DateTime constructor accepts invalid TZ abbreviations
Description:
------------
PHP will accept invalid DST-related time zone abbreviations, e.g. daylight
savings time when daylight savings time cannot be in effect on the given
date;
subsequent operations on the returned object may produce invalid results.
This should produce an error.
Test script:
---------------
$dt = new DateTime('1980-01-01 15:00:00 PDT');
print_r($dt);
$dt->modify('+1 hour');
print_r($dt);
Expected result:
----------------
EXPECTED output should be an error.
Actual result:
--------------
DateTime Object
(
[date] => 1980-01-01 15:00:00
[timezone_type] => 2
[timezone] => PDT
)
DateTime Object
(
[date] => 1980-01-01 15:00:00
[timezone_type] => 2
[timezone] => PDT
)
Note that PDT is invalid for the given date, and the modify() call didn't
work
and also didn't throw an error.
