Further comments

I took the test cases from after.spec.ts and before.spec.ts and added new logic to test cases to check beforeOrEqual/afterOrEqual validators.

The tests are failing. Can you please look into it?

I think previously the test work fine when time is after or equal to the defined interval fails because the tested DateTime is executed first (which may have milliseconds: 300) , and the DateTime that produced afterward during the validation in the "Validations/date/helpers/offset.ts" files would have milliseconds: 500, thus making the tested DateTime would always lesser than the DateTime that use compile(30, "minutes").

So I have done some modification in that test case by adding a max milliseconds and seconds in the tested DateTime to force them compare minutes only.
