[12.x] feat: add now methods to Date rule

[calebdw]

Hello!

Motivation

I just had a bug in production where a developer (me :upside_down_face:) was validating a datetime with:

'request_at'  => [Rule::date()->beforeOrEqual(now())],

However, this caused failures when the datetime was the current day and had a time component. The fix was:

'request_at'  => [Rule::date()->beforeOrEqual('now')], // do not use now()

which is not very elegant and requires a comment to prevent future develepers from causing a regression.

Additionally, we have a ton of datetime fields that need to be validated and don't want to have to repeatedly specify ->format('Y-m-d H:i:s')

Solution

What I would like is

'request_at'  => [Rule::date()->andTime()->nowOrBefore()],

This adds the following methods to the Date validation rule:

• beforeNow
• afterNow
• nowOrBefore
• nowOrAfter
• andTime

Thanks!
