Users who run 'date' will get the 88fdf5721SBaptiste Daroussin# time zone abbreviation "-00", indicating that the actual time zone 98fdf5721SBaptiste Daroussin# is unknown. 101315084cSEdwin Groothuis 11*46226b01SPhilip Paeps# TZ="Factory" was added to TZDB in 1989, and in 2016 its abbreviation 12*46226b01SPhilip Paeps# was changed to "-00" from a longish English-language error message. 13*46226b01SPhilip Paeps# Around 2010, CLDR added "Etc/Unknown" for use with TZDB, to stand 14*46226b01SPhilip Paeps# for an unknown or invalid time zone. These two notions differ: 15*46226b01SPhilip Paeps# TZ="Factory" is a valid timezone, so tzalloc("Factory") succeeds, whereas 16*46226b01SPhilip Paeps# TZ="Etc/Unknown" is invalid and tzalloc("Etc/Unknown") fails. 17*46226b01SPhilip Paeps# Also, a downstream distributor could modify Factory to be a 18*46226b01SPhilip Paeps# default timezone suitable for the devices it manufactures, 19*46226b01SPhilip Paeps# whereas that cannot happen for Etc/Unknown. 20*46226b01SPhilip Paeps 212865ab3fSPhilip Paeps# Zone NAME STDOFF RULES FORMAT 222289da42SEdwin GroothuisZone Factory 0 - "Local time zone must be set--use tzsetup" 23
