Hello all, Regarding the last Time Zone Data, two possible corrections could be applied for Chile rules (southamerica file) 1. Rules are pointed to Zone America/Santiago and Pacific/Easter. But it missing the links to Chile/Continental and Chile/EasterIsland. We tested in a Solaris 10 server with TZ=Chile/Continental and the new rules were not applied. So the following two lines should be applied at the end of Chile section: Link America/Santiago Chile/Continental Link Pacific/Easter Chile/EasterIsland 2. The following suggestion is about how it is defined the Time Zone for Chile and if it applies DST or not. This change is to keep an accurate time zone defined, CLT or CLST, this year. Before May 15th the Time Zone is CLT (UTC -3). If we applied the new rules now, the time zone will be CLST (UTC -3) until May 15th. The time will be fine, but the timezone is not ok. My suggestion is to add the following lines marked in red in the Zone section: # Zone NAME GMTOFF RULES FORMAT [UNTIL] Zone America/Santiago -4:42:46 - LMT 1890 -4:42:46 - SMT 1910 Jan 10 # Santiago Mean Time -5:00 - CLT 1916 Jul 1 # Chile Time -4:42:46 - SMT 1918 Sep 10 -4:00 - CLT 1919 Jul 1 -4:42:46 - SMT 1927 Sep 1 -5:00 Chile CL%sT 1932 Sep 1 -4:00 - CLT 1942 Jun 1 -5:00 - CLT 1942 Aug 1 -4:00 - CLT 1946 Jul 15 -4:00 1:00 CLST 1946 Sep 1 # central Chile -4:00 - CLT 1947 Apr 1 -5:00 - CLT 1947 May 21 23:00 -4:00 Chile CL%sT 2015 Apr 26 3:00u -3:00 Chile CLT 2016 May 15 3:00u -4:00 Chile CL%sT Zone Pacific/Easter -7:17:28 - LMT 1890 -7:17:28 - EMT 1932 Sep # Easter Mean Time -7:00 Chile EAS%sT 1982 Mar 14 3:00u # Easter Time -6:00 Chile EAS%sT 2015 Apr 26 3:00u -5:00 Chile EAST 2016 May 15 3:00u -6:00 Chile EAS%sT Regards, Carlos Huenchullán
