[conspire] A matter of time (zones and changes)

[Michael Paoli]

A yes, that's why we have timezone files.  Also handles when the
rules/laws changes, and varies year-to-year.

(for TZ in \
US/Pacific PST8PDT America/Vancouver America/Edmonton America/Inuvik
do
zdump -v "$TZ" | grep 'Nov.*2026'; echo
done)
US/Pacific  Sun Nov  1 08:59:59 2026 UT = Sun Nov  1 01:59:59 2026 PDT
isdst=1 gmtoff=-25200
US/Pacific  Sun Nov  1 09:00:00 2026 UT = Sun Nov  1 01:00:00 2026 PST
isdst=0 gmtoff=-28800

PST8PDT  Sun Nov  1 08:59:59 2026 UT = Sun Nov  1 01:59:59 2026 PDT
isdst=1 gmtoff=-25200
PST8PDT  Sun Nov  1 09:00:00 2026 UT = Sun Nov  1 01:00:00 2026 PST

Notice also for those Canadian zones, zone abbreviation change too.
And that's not a list of all the zones that changed
since last year, but a few I easily picked out, and US/Pacific /
PST8PDT for comparison.
