Wrong minutes and seconds in a JavaScript date before year 1925 [duplicate]

Question

I have an application which allows users to pick some time slots. By default the timeslots are empty, and my .NET back-end has default generated values of type DateTimeOffset, which by default are set to "0001-01-01T00:00:00+00:00".

Now, when I populate a date on the front-end with this value, it generates a date in the local time zone, but with wrong minutes and seconds. This happens only in Chrome. I'm not seeing this under Edge or Firefox.

console.log(new Date("2001-01-01T00:00:00+00:00").toString())
// Mon Jan 01 2001 02:00:00 GMT+0200 (Eastern European Standard Time)
console.log(new Date("1001-01-01T00:00:00+00:00").toString())
//Thu Jan 01 1001 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1801-01-01T00:00:00+00:00").toString())
//Thu Jan 01 1801 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1901-01-01T00:00:00+00:00").toString())
//Tue Jan 01 1901 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1961-01-01T00:00:00+00:00").toString())
//Sun Jan 01 1961 03:00:00 GMT+0300 (Eastern European Standard Time)
console.log(new Date("1921-01-01T00:00:00+00:00").toString())
//Sat Jan 01 1921 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1931-01-01T00:00:00+00:00").toString())
//Thu Jan 01 1931 03:00:00 GMT+0300 (Eastern European Standard Time)
console.log(new Date("1922-01-01T00:00:00+00:00").toString())
//Sun Jan 01 1922 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1923-01-01T00:00:00+00:00").toString())
//Mon Jan 01 1923 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1924-01-01T00:00:00+00:00").toString())
//Tue Jan 01 1924 02:02:04 GMT+0202 (Eastern European Standard Time)
console.log(new Date("1925-01-01T00:00:00+00:00").toString())
//Thu Jan 01 1925 02:00:00 GMT+0200 (Eastern European Standard Time)

As you can see, I played around with the date, to see before which date this happens, but the problem may not be the year 1925, just certain time before the current date. Does anyone know why this is happening?

Prior to 1883 Time Zones were not standardized. If you check every year you'll notice that 1883 is "broken" with the additional minutes and 1884 is "fine". Chrome handles this transition very well - you'll notice the "problem" doesn't exist in Firefox.

new Date("1883-01-01T00:00:00+00:00")
Sun Dec 31 1882 16:07:02 GMT-0752 (Pacific Standard Time)
new Date("1884-01-01T00:00:00+00:00")
Mon Dec 31 1883 16:00:00 GMT-0800 (Pacific Standard Time)

In fact, you can track this down to November 18th, 1883.

new Date("1883-11-18T00:00:00+00:00")
Sat Nov 17 1883 16:07:02 GMT-0752 (Pacific Standard Time)
new Date("1883-11-19T00:00:00+00:00")
Sun Nov 18 1883 16:00:00 GMT-0800 (Pacific Standard Time)

Chrome tries very hard to match time, even going so far as to calculate the suspended DST of Ramadan in Egypt in 2010.
