Converting timezones in javascript resulted in very strange results, am I doing something wrong or is it a bug?

问题

After isolating the problem in my current project .... I think something is not working currently with the Date object in javascript.

But I don't want to be arrogant because maybe I am doing something wrong, is it a bug? or am I doning something wrong?

---

I want to convert a date to diffrent time zone in javascript, I made this function:

function ConvertToTimeZone(date, timezone) {
   let convertedTimeString = date.toLocaleString("en-US", {hour12: false, timeZone: timezone})
   return new Date(convertedTimeString)
}

Then I am using it like this:

let testDate = new Date("Thu May 21 2020 17:04:05 GMT-0700 (Pacific Daylight Time)");
let convertedDate = ConvertToTimeZone(testDate, "Europe/London");

Or like this:

let testDate = new Date("Thu May 21 2020 18:04:05 GMT-0700 (Pacific Daylight Time)");
let convertedDate = ConvertToTimeZone(testDate, "UTC");

But something wrong is happening when I use this date:

let testDate = new Date("Thu May 21 2020 17:04:05 GMT-0700 (Pacific Daylight Time)");
let convertedDate = ConvertToTimeZone(testDate, "UTC");

with that last exmaple convertedDate end up with Invalid Date {}

And when I look closely in my ConvertToTimeZone the result of date.toLocaleString(...) is 5/22/2020, 24:04:05 which looks strange because the hours of that time cannot be 24 (it should be 0)
