Some Teslas in British Columbia set their clocks back one hour on Sunday, Nov. 1, even though the province no longer changes its clocks. Drive Tesla Canada says it confirmed the problem in one of its own cars after reports from several owners.
Who is affected
The bug appears to affect cars without Full Self-Driving that run software 2026.38.3.2 or 2026.38.5.1. Their clocks show a time one hour early. Owners cannot set the clock manually, so a fix will have to come in a Tesla software update. Drive Tesla Canada says Tesla had not answered its request for comment.
Why B.C. is different
British Columbia's spring change on March 8, 2026, was its last; the province now stays at UTC-7 all year. Washington state and most of North America fell back on Nov. 1, leaving B.C. an hour ahead of its neighbour.
IANA's Time Zone Database release 2026b records the move to permanent -07. To work around limits in the Unicode CLDR and ICU libraries, it temporarily models the change as happening on Nov. 1, 2026, at 2:00. It also warns that files built with older zic versions can cause some readers to ignore America/Vancouver's Nov. 1 transition. It is not known whether this is behind the Tesla bug.
What to check
If you set charging or preconditioning by time, it may run an hour off until the update arrives.
