# Fiji, prime minister Josaia Voreqe "Frank" Bainimarama announced the
# suspension of DST for the 2021/2022 season: "Given that we are in the process
# of readjusting in the midst of so many changes, we will also put Daylight
# Savings Time on hold for this year. It will also make the reopening of
# scheduled commercial air service much smoother if we don't have to be
# concerned shifting arrival and departure times, which may look like a simple
# thing but requires some significant logistical adjustments domestically and
# internationally."
