Casey time zone change
Based on information we have received from the Australian Antarctic Division, Casey station and Macquarie Island station will move to Tasmanian daylight savings time on Sunday 4 October. This will take effect from 0001hrs on Sunday 4 October 2020 and will mean Casey and Macquarie Island will be on the same time zone as Hobart. Some past dates too for this 3 hour time change back and forth between UTC+8 and UTC+11 for Casey: - 2018 Oct 7 4:00 - 2019 Mar 17 3:00 - 2019 Oct 6 3:00 - 2020 Mar 8 3:00 and now - 2020 Oct 4 0:01 Best regards, Steffen - timeanddate.com
Thanks for the heads-up about Casey. Reading between the lines of your message, it appears that we also need an update for Macquarie Island. tzdb has Macquarie at +11 all year due to email you sent us on 2010-03-10. However, that experiment lasted just one year according to your records at timeanddate.com, and Macquarie has used Tasmanian rules since then. Proposed patch attached. We're about to do a new release anyway because of Yukon and so might as well fold this in.
Actually I need to correct myself on one of dates: The October 2019 change was 2 days earlier, 4 October 2019. On 2020-10-02 09:05, Paul Eggert wrote:
