Stephen Colebourne claimed that CLDR determines whether to use the standard or daylight time strings by comparing the "raw offset" (presumably meaning "the offset during standard time") with the "actual offset" (presumably meaning "the offset during daylight savings time").

Therefore, it *must* know those offsets, otherwise it cannot compare them.

So let me rephrase the question:

	How does CLDR obtain those offsets?
