"America/Santiago" timezone problem #210

Closed gv-rayalab closed 9 years ago

gv-rayalab commented 9 years ago

Chile is now excempt from the Daylight Saving time, so the time in the new 0.3.1 version is wrong.

This was done in tzdb 2015a. This isn't linked from the home page, but is available if you pull from the github repo.

Admittedly, we need to do a better job of staying on top of tzdb updates. #205 is still pending for 2015c, and already 2015d is out and needs packaging.

Is this fixed? I am getting wrong offset for America/Santiago with 0.5.23

utc: 2019-04-22T12:00:00Z
America/Santiago: 2019-04-22T08:00:00-04:00

At the moment the correct DST offset is -03:00

I'm using the latest moment and moment-timezone: "moment": "^2.29.1", "moment-timezone": "^0.5.32"

and

moment().tz("America/Santiago").format()

Is returning 2021-01-08T19:28:30-03:00 while its actually 2021-01-08T18:28:30-04:00

**In case someone else is encountering this issue.

America/Santiago refers to Chile and not Dominican Republic**

@yankopetrov - In 2019 the change from UTC-3 to UTC-4 occurred on April 7th, so the conversion is correct. https://www.timeanddate.com/time/zone/chile/santiago?year=2019

@tomerb15 - In 2021, the offset for January is indeed UTC-3, so again the conversion is correct. https://www.timeanddate.com/time/zone/chile/santiago?year=2021

La hora de verano en Chile se produce el primer sábado de septiembre y finaliza el primero sábado de abril. Moment con timezone me entrega una isDST equivocado.
