How to expect the date to contain another date in Cypress?

This would be silliest question which I am asking here. I was going through Cypress automation and was working on one of the scenario.

I wanted to verify whether the date is matching or containing the date or not.

System date – 11/30/2021 06:18:33 PM and derived application date – 11/30/2021 6:18:38

How can I match and assert this using Cypress?

expect('11/30/2021 06:18:33 PM').to.have.string('11/30/2021 6:18:38');

I am getting below error :-

AssertionError

expected '11/30/2021 06:18:33 PM' to contain '11/30/2021 6:18:38'
