This is not bogus. Maybe "won't fix" but definitely not bogus.
Please note that I am quite familiar with object comparison in PHP. The
documenation says: "When using the comparison operator (==), object
variables are compared in a simple manner, namely: Two object instances
are equal if they have the same attributes and values, and are instances
of the same class."
Indeed, AS I POINTED OUT IN THE DESCRIPTION, other built-in objects in
PHP demonstrate the correct/expected behavior:
$a = new Exception("foo");
$b = new Exception("bar");
$c = new Exception("foo");
var_export($a == $b); // Outputs: FALSE
var_export($a == $c); // Outputs: TRUE
A DateTime object have very obvious properties (namely the date/time
value contained, possibly time zone of other info specified). The
equality check (NOT IDENTITY CHECK) should be comparing those values,
as apparently it does for Exception.

Thank you for taking the time to write to us, but this is not
a bug. Please double-check the documentation available at
http://www.php.net/manual/ and the instructions on how to report
a bug at http://bugs.php.net/how-to-report.php
Read on object comparison in PHP, what you are attempting will not
work.
if you want to compare 2 dates, convert them to unix timestamps first.

Description:
------------
The equality check (==) for DateTime objects does not actually check
the properties of the object (i.e. the internally stored date). This
is very counter-intuitive as it does not follow the behavior of
user-created objects or even other internal PHP objects like Exception.
Reproduce code:
---------------
$d1 = new DateTime("2001-01-01");
$d2 = new DateTime("2007-02-28");
print "DateTime Equal? " . var_export($d1 == $d2, true) . "\n";
Expected result:
----------------
DateTime Equal? false
Actual result:
--------------
DateTime Equal? true
