tzdb data for noncommittal factory settings
This file is in the public domain, so clarified as of

For distributors who don't want to specify a timezone in their
installation procedures. Users who run 'date' will get the
time zone abbreviation "-00", indicating that the actual time zone
is unknown.
TZ="Factory" was added to TZDB in 1989, and in 2016 its abbreviation
was changed to "-00" from a longish English-language error message.
Around 2010, CLDR added "Etc/Unknown" for use with TZDB, to stand
for an unknown or invalid time zone. These two notions differ:
TZ="Factory" is a valid timezone, so tzalloc("Factory") succeeds, whereas
TZ="Etc/Unknown" is invalid and tzalloc("Etc/Unknown") fails.
Also, a downstream distributor could modify Factory to be a
default timezone suitable for the devices it manufactures,
whereas that cannot happen for Etc/Unknown.
