Although this issue is a close call, we took the approach noted in the
NEWS file for the recent Chile change: "call the period from 2014-09-07
through 2016-05-14 daylight saving time instead of standard time, as
that seems more appropriate now".
When countries go on daylight saving time indefinitely, we prefer to
call it standard time (as that is what it is, in practice). That is what
we thought Chile was doing, before 2016c. However, Chile went off DST
after a year and a half, and when there are shorter periods like that we
have tended to call it year-long DST.
