Resolves #1462


What?

This PR introduces a new validation rule, DateTimeDiff wich validates the difference of date/time against a specific rule.

The $type argument on our construct should follow PHP's DateInterval properties. So we can use types such as year, months,days,full days,hours,minutes,seconds,microseconds.


Note: This is my first PR in a relatively large open-source project, so if I've done anything incorrectly, please let me know. 👍

If we are going to use this, I believe that we can improve to a Enum file. I didn't create because the project don't have any

I know this seems weird, but i wanted to use those DateInterval vars. what do you guys think about it? How do we can improve this validation?

@gvieiragoulart I approved the CI run. There are some static analysis checks you'll need to fix before we can merge this!

I'll keep an eye here to approve the CI run again as soon as you fix them, and once it passes, I'll do a full review!

This was like that on purpose, it's a literal constant. See https://phpstan.org/writing-php-code/phpdoc-types#literals-and-constants

I'm a against adding documentation to the code like that, I think the name of the parameter should be pretty obvious for what it does, otherwise we should do that for everything. I understand that it can be useful to add some documentation here and there, but for this specific method, I would rather not have it.

I do understand the appeal of using DateInterval formats directly. However, I think having more descriptive values is better as it's more understandable. With the literal constant, there's no reason to translate or document anything.

Very nice catch!

Not sure if that's correct, because days can return false

I mixed some of my changes and yours @gvieiragoulart! Here's the merge request: #1475

I'm not sure whether we should add full days or not yet, it can be useful, but it doesn't seem necessary. What are your thoughts?
