November 1 time-zone changes in parts of Canada could leave Android clocks and Google Calendar events an hour off

Android Authority, citing Google, reports that outdated Android phones in parts of Canada could mistakenly turn their clocks back on November 1, when those regions stop changing clocks seasonally. Some Google Calendar events scheduled for that date or later could appear an hour later than intended. Google says it will automatically adjust most affected events, but some may need manual fixes; warning badges appear only on Calendar’s web version.
