Invalid DST for America/Santiago

Open alexmichailichenko opened this issue 3 years ago • 1 comments

Describe the bug Seems like dayjs doesn't take into account that Chile's 2022 DST start is delayed from September 2 to September 11 (Internal Affairs Ministry of Chile informed the DST for America/Santiago to start at midnight on September 11 due to the vote on the new Constitution). America:Santiago

Expected behavior Should return a string with the time 09:00, but returns 2022-09-10T10:00:00-03:00 for 2022-09-10T13:00:00.000Z

Information

  • Day.js Version 1.11.5
  • OS: all
  • Browser all
  • Time zone: America/Santiago

I'm not 100% sure, but it seems dayjs is using Intl. Intl in browsers relys on system time. Can you please check if OS timezone is correct?
