Incorrect result of deepEqual for dates

[skisor]

Try

is.deepEqual(new Date("2012-12-12T00:30:00.000Z"), new Date("2021-11-11T13:12:00.000Z"))

Expected

false because dates are different (timestamps are 1355272200000 and 1636636320000)

Actual

true

"is" version: 1.0.2
node: 6.2.0

Hi @skisor , the current version of deepEqual only counts for Arrays and generic Objects, so two Date objects are considered equal if they have the same set of own, enumerable and string-keyed properties. This will be fixed in the next version.

This bug have been unsolved for very long time? Maybe this repo could give a few ideas? https://github.com/zubuzon/kewlr
