Actually... No.
Date doesn't parse this to local environment time.
That string contains T00:00:00.000Z.It is timezone of date(UTC in current case) . So it will convert correct in every environment!

Exactly what I was saying, that this is only valid when that timezone containing string is generated in the same environment. I'm living in UTC+2 and parsing the string withe Zulu Z time in the end (set time to 23h to make the point):

new Date("2019-08-02T23:00:00.000Z").toLocaleDateString("sq-AL",{ year: 'numeric', month: '2-digit', day: '2-digit' });

returns 08/03/2019

That is way it is good practis to set all servers in utc

But you can not guarantee users with their computers to stay put in UTC too. Nobody told the string was parsed in server. If it was though then the split method just calls for SQL injection attack.

Also no sane person ever thought "put all your servers in the wrong timezone" was a good idea.

Instead of trying to work around bugs in your code by making every single recorded time in your server wrong, just learn the involved concepts and the available APIs.
