The TIME_ZONES table predates several tz releases, so 32 zones give the
wrong UTC offset today or within the next year when the device applies
the string with setenv("TZ"): Mexico (no DST since 2022), Egypt (DST
again since 2023), Kazakhstan, Morocco, Paraguay, Iran, Jordan, Syria,
Greenland, and from 1 November 2026 British Columbia, Alberta, the
Northwest Territories and Manitoba (permanent UTC-7, -6, -6 and -5).
Each value is now the POSIX TZ footer of the zone's TZif file in IANA
tz 2026e (PyPI tzdata 2026.5). The keys and their order are unchanged.
"UNK" abbreviations become the numeric <+01> form, which newlib accepts.
America/Godthab and America/Scoresbysund still show summer time from
1 January to the last Sunday in March on newlib: their rule time is
negative (M3.5.0/-1) and newlib's tzset reads it as unsigned. That is
a newlib bug, not a table error.
