Description

I just learned that Date constructor accepts Date since ES6.

If Type(value) is Object and value has a [[DateValue]] internal slot, then
Let tv be thisTimeValue(value).

https://262.ecma-international.org/6.0/#sec-date-constructor

Fail

new Date(date.getTime());

new Date(
	date.getFullYear(),
	date.getMonth(),
	date.getDate(),
	date.getHours(),
	date.getMinutes(),
	date.getSeconds(),
	date.getMilliseconds(),
);

Pass

new Date(date)

Proposed rule name

consistent-date-clone

Additional Info

Note: new Date(date) doesn't work before ES6

Let v be ToPrimitive(value).
If Type(v) is String, then
Parse v as a date, in exactly the same manner as for the parse method (15.9.4.2); let V be the time value for this date.
Else, let V be ToNumber(v).
Set the [[PrimitiveValue]] internal property of the newly constructed object to TimeClip(V) and return
