Can you please explain me how these structures in tzdata2016c work to accomplish the necessary TZ change in Chile.
Before the transition, this rule line is active: Rule Chile 2012 2014 - Sep Sun>=2 4:00u 1:00 S so Chile is assumed to be on daylight saving time, i.e., -03. You can verify this by running 'zdump -c2016,2017 -v America/Santiago'. Its output should contain: America/Santiago Sun May 15 02:59:59 2016 UT = Sat May 14 23:59:59 2016 CLST isdst=1 gmtoff=-10800 America/Santiago Sun May 15 03:00:00 2016 UT = Sat May 14 23:00:00 2016 CLT isdst=0 gmtoff=-14400
