I was about to bump TZ on illumos (the open-source inheritor of what was OpenSolaris) but I encountered these when building: "europe", line 2551: warning: time zone abbreviation differs from POSIX standard (+03) "europe", line 2552: warning: time zone abbreviation differs from POSIX standard (+05) (rule from "europe", line 599) "europe", line 2552: warning: time zone abbreviation differs from POSIX standard (+04) (rule from "europe", line 600) "europe", line 2627: warning: time zone abbreviation differs from POSIX standard (+03) "europe", line 2628: warning: time zone abbreviation differs from POSIX standard (+05) (rule from "europe", line 599) "europe", line 2628: warning: time zone abbreviation differs from POSIX standard (+04) (rule from "europe", line 600) "europe", line 2630: warning: time zone abbreviation differs from POSIX standard (+02) (rule from "europe", line 603) "europe", line 2711: warning: time zone abbreviation differs from POSIX standard (+06) "europe", line 2712: warning: time zone abbreviation differs from POSIX standard (+08) (rule from "europe", line 599) "europe", line 2712: warning: time zone abbreviation differs from POSIX standard (+07) (rule from "europe", line 600) Now it is possible that the zic(1) utility for illumos needs some updating. OTOH, I've never had a problem until this specific update. The entries in question are (with markings): Zone Europe/Astrakhan 3:12:12 - LMT 1924 May **HERE*** 3:00 - +03 1930 Jun 21 **HERE*** 4:00 Russia +04/+05 1989 Mar 26 2:00s 3:00 Russia +03/+04 1991 Mar 31 2:00s 4:00 - +04 1992 Mar 29 2:00s 3:00 Russia +03/+04 2011 Mar 27 2:00s 4:00 - +04 2014 Oct 26 2:00s 3:00 - +03 2016 Mar 27 2:00s 4:00 - +04 Zone Europe/Ulyanovsk 3:13:36 - LMT 1919 Jul 1 2:00 **HERE*** 3:00 - +03 1930 Jun 21 **HERE*** 4:00 Russia +04/+05 1989 Mar 26 2:00s 3:00 Russia +03/+04 1991 Mar 31 2:00s **HERE*** 2:00 Russia +02/+03 1992 Jan 19 2:00s 3:00 Russia +03/+04 2011 Mar 27 2:00s 4:00 - +04 2014 Oct 26 2:00s 3:00 - +03 2016 Mar 27 2:00s 4:00 - +04 Zone Asia/Barnaul 5:35:00 - LMT 1919 Dec 10 **HERE*** 6:00 - +06 1930 Jun 21 **HERE*** 7:00 Russia +07/+08 1991 Mar 31 2:00s 6:00 Russia +06/+07 1992 Jan 19 2:00s 7:00 Russia +07/+08 1995 May 28 6:00 Russia +06/+07 2011 Mar 27 2:00s 7:00 - +07 2014 Oct 26 2:00s 6:00 - +06 2016 Mar 27 2:00s 7:00 - +07 I checked the mailing list archives quickly, but didn't see anything about Astrakhan, so I figured nobody else has seen this yet. I'm no expert in these... I just happen to update the illumos ones for the community every time my distro (OmniOS) gets ready to ship an update. Thanks, Dan McDonald -- OmniOS Engineering
