Fixes changeset being empty when datetime change is sub second

Q	A
Type	fix
BC Break	no
Fixed issues	#2538

Summary

The ODM was ignoring changes when they are under a second (because of the cast as timestmap).

It might be a BC break because people can rely on the old behavior ?

(I do not have a local setup with mongo, so I'm sort of using the actions to test.. sorry about that)

edit : I just saw that I can enable them in my fork, i'll test there :)

LGTM with the PHPCS fix and suppression.

if you know how to fix the style issue, feel free to fix it directly there if you want to save some time to restart the checks later ^^

Thanks !

It goes like this:

mongodb-odm/lib/Doctrine/ODM/MongoDB/Tools/Console/Command/Schema/ValidateCommand.php

Lines 44 to 45 in 8e0deb1

	// phpcs:ignore SlevomatCodingStandard.Operators.DisallowEqualOperators.DisallowedEqualOperator
	if ($meta == unserialize(serialize($meta))) {
