Thanks for the pointer to that informative article by Dan Goodin. I passed it along my sysadmins. A quick Google search says users have also reported that Microsoft Windows can change its time zone spontaneously - that is, time zone travel rather than time travel. I didn't find an explanation for this other phenomenon. See, for example: https://www.reddit.com/r/Windows11/comments/rqu739/windows_changes_to_wrong_... https://answers.microsoft.com/en-us/windows/forum/all/time-zone-keeps-changi...
