I am trying to display a date in javascript. I receive the date from backend like this: 2020-09-22T17:10:25Z (from and Instant object in Java).

When I try to call new Date("2020-09-22T17:10:25Z") I get: Tue Sep 22 2020 20:10:25 GMT+0300 (Eastern European Summer Time). The issue with this is that I am not in a GMT+0300 timezone but rather GMT+0200.

When I try to call new Date() on the other hand I get Thu Dec 08 2022 20:34:11 GMT+0200 (Eastern European Standard Time) which is my correct timezone.

My question is, why in the first case I get the GMT+0300 and in the second case I get GMT+0200? The Z in the string I am trying to parse stands for Zulu or zero hour offset, so why does the 2 different approaches use different timezones?

>Solution :

It looks like you are in GMT+2 in winter, but in summer (in September) you are in summer time which is GMT+3
