Briefly:
Fiji ends DST 2019-01-13, not 2019-01-20.
Most of Chile changes DST dates, effective 2019-04-06.

Changes to future timestamps

Fiji ends DST 2019-01-13 instead of the 2019-01-20 previously
predicted. (Thanks to Raymond Kumar.) Adjust future predictions
accordingly.

Most of Chile will end DST on the first Saturday in April at 24:00 mainland
time, and resume DST on the first Saturday in September at 24:00 mainland
time. The changes are effective from 2019-04-06, and do not affect the
Magallanes region modeled by America/Punta_Arenas. (Thanks to Juan Correa
and Tim Parenti.) Adjust future predictions accordingly.

# Translating the captions on the video at 0:44-0:55, "We want to announce as
# Government that from 2019, Winter Time will be increased to 5 months, between
# the first Saturday of April and the first Saturday of September."
# At 2:08-2:20, "The Magallanes region will maintain its current time, as
# decided by the citizens during 2017, but our Government will promote a
# regional dialogue table to gather their opinion on this matter."

# "We will keep the new time policy unchanged for at least the next 4 years."
# So we extend the new rules on Saturdays at 24:00 mainland time indefinitely.
