Some historical information about tz code.
by Random832 March 15, 2016

March 15, 2016

(Posted to both The Unix Heritage Society and the TZ mailing list) I've been off-and-on reading the "live minus thirty years" old usenet feed at olduse.net, and noticed something that may be of interest to both of these groups: The original mod.sources posting of the (as far as I can tell) earliest available version of Arthur David Olson's timezone handling code, in 1986. https://groups.google.com/d/msg/mod.sources/gcolqTxTt9w/04ZtaYCxLvcJ For the files present in both, it matches revision 7441f6b6 from the git repository, except for SCCS IDs vs %W%. https://github.com/eggert/tz/tree/7441f6b6705782743f40b9fc40cdcc80a498fda5 The git repository contains a file ialloc.c that is not present in the release. Probable renamed files - These appear in the git repository under their new names, but had the older names in the release. New: localtime.c newctime.3 zdump.c zic.8 zic.c Old: tzcomp.8 tzcomp.c tzdump.c settz.c settz.3 Files in the release but not this version of the git repository: mkdir.c strchr.c: These never appear, though they're referenced in Makefile edits. pacificnew: doesn't appear until SCCS version 8.1 in revision aaf2a927 dated July 2006. years.sh: Appears as SCCS 7.1 yearistype.sh, dated March 1992.

Status in the Carribean
by Steve Jones March 14, 2016

March 14, 2016

It's been a busy time in the Carribean, what with Quitana Roo, Turks & Caicos, and now Haiti. I've updated an image that reflects the new current status of that region: http://OnTimeZone.com/images/caribbean.gif (magenta lines = time zone borders) (blue lines = dst observance borders) Over water, the lines were not drawn to be "anatomically correct", though they lie on the correct side of any island.
