Chile actually decides on and publishes their DST/ST dates year by year so there's rarely consistency (it's the Ministry of Energy, to be exact). One year they did away with DST fully, and then reinstated it the next. Most of my flights around those times of year had incorrect in-flight times/dates, schedules were updated at the last minute, etc. I feel the OP's pain.
