3. If NewTarget is not undefined, then
a. If Type(value) is Object and value has a [[DateValue]] internal slot, then
i. Let tv be thisTimeValue(value).
b. Else,
i. Let v be ? ToPrimitive(value).

ToPrimitive ( input [ , PreferredType ] )
1. If PreferredType was not passed, let hint be "default".
2. Else if PreferredType is hint String, let hint be "string".
3. Else PreferredType is hint Number, let hint be "number".
4. Let exoticToPrim be ? GetMethod(input, @@toPrimitive).
5. If exoticToPrim is not undefined, then
a. Let result be ? Call(exoticToPrim, input, « hint »).
