Javascript new Date(number) but produced different timezone (Malaysia)

Question

Important notes:

The machine's date & time setting is the automatic setting
The machine is located in Malaysia, and the timezone is GMT +8
Malaysia do not have daylight saving

Question:

When using the Date constructor with the number value which representing the number of milliseconds since January 1, 1970, 00:00:00 UTC. These two numbers (378000000000, 379000000000) are giving different timezone.

This was tested in both Chrome devtool console and node.js, they're giving the same result. Came across this post but it doesn't seems relevant.

Any clue / explanation please?

Below is the quick snippet and the screenshot of result

console.log(new Date(378000000000).toString());
console.log(new Date(378000000000).toLocaleString());
console.log('-----------');
console.log(new Date(379000000000).toString());
console.log(new Date(379000000000).toLocaleString());

Googled "malaysia timezone change in 1982" ... https://en.wikipedia.org/wiki/Time_in_Malaysia - it's amazing what you can find on the "internets" :p — Jaromanda X, Jun 26 '18 at 07:16

You have to use the getTimezoneOffset() method. For example:

const melissaBirthdayParty = new Date();
let birthdayPartyTime = melissaBirthdayParty.getTimezoneOffset();
console.log("The party is at " + birthdayPartyTime)
