The query is what does the (CLDR/ICU) label apply to: the offset or the time
The label would seem to apply to the period of Location Summer Time, Location
Winter Time, Location Daylight Saving Time, Location Standard Time, rather than
denoting the time zone offset.
So what then should you label the extra periods: use the same labels as the
previous uses of the same offsets, or give the extra periods their own unique
labels, and what should those unique labels indicate?
