well, it certainly would if it were named somethign like "is_dst", but in
the intereast of abslute calrity, how about we add something like:

"This member can not be set to force the DST adjustment to behave any
differently than the tzinfo object implements it."

and/or

"This  member is not an indicator of whether DST is currently in effect,
but is only an indicator or which offset to use in ambiguous cases."
