Sorry, I now see that this may actually be a timezone specific issue which I can now reproduce in Windows by changing the timezone of the timeseries to "Pacific/Auckland".
This would indicate that macos-arm64 CRAN machines are based in a different timezone than the other machines, not the arm64 OS as such. This reminds me that I ran into a similar issues earlier this year where I struggled to get GitHub Actions to run the macos workflow in a non-default timezone, which I raised elsewhere: https://community.rstudio.com/t/upgrading-github-action-workflow-to-address-no-package-called-rcmdcheck-but-unclear-how-to-account-for-timezone/166876 ... I should have thought about that first.
