# For a brief period of roughly six weeks in 1946, DST was only observed on an
# emergency basis in specific regions of central Chile; namely, "the national
# territory between the provinces of Coquimbo and Concepción, inclusive".
# This was enacted by Decree 3,891, dated 1946-07-13, and took effect

# https://www.diariooficial.interior.gob.cl/versiones-anteriores/do-h/19460715/#page/1
# The decree contemplated "[t]hat this advancement of the Official Time, even
# though it has been proposed for the cities of Santiago and Valparaíso only,
# must be agreed with that of other cities, due to the connection of various
# activities that require it, such as, for example, the operation of rail
# services". It was originally set to expire after 30 days but was extended
