The news from Honduras means that as of Monday morning (August 7) the tz database is incorrect for today's time stamps in that country, so it's time to push out a new version of the data. Here's a proposed patch incorporating all the proposed changes since the last data update. Thanks to everybody who has contributed fixes and news; the work couldn't be done without you. Data changes affecting current or future time stamps Honduras stopped observing DST on Monday at 00:00. (Thanks to Jesper Norgaard Welen.) America/Bermuda will follow the US's lead next year. No word yet on Bahamas, Cuba, Haiti, Mexico, and Turks and Caicos, so we leave those alone for now. America/Moncton will use US-style rules next year, switching at 02:00 rather than at 00:01. (Thanks to Chris Walton.) New Zone America/Blanc-Sablon, for Canadians who observe AST all year. (Thanks to Chris Walton.) Data changes affecting historical time stamps New Zone Europe/Volgograd, to reflect the fact that its area has a unique time zone history since 1970. (Thanks to Jesper Norgaard Welen.) Europe/Samara was not called "Kuybyshev" until 1935-01-27. Corrected longitudes for America/Scoresbysund, affecting LMT before 1916. Similarly for America/Rankin_Inlet, America/Inuvik. (Thanks to Andy McDonald.) Administrative data changes New Zone America/Atikokan, superseding the far less-populous America/Coral_Harbour. A backwards-compatible entry is added for those who prefer the old name. (Thanks to Chris Walton.) New Zones Europe/Jersey, Europe/Guernsey, Europe/Isle_of_Man to match the new ISO 3166 (inhabited) country codes. These are merely links to Europe/London for now, though I suppose at some point we could research them for pre-1970 divergences. In zone.tab, fix latitude and longitude for America/Argentina/Tucuman. (Thanks to Andy McDonald.) In zone.tab, update commentary for Canadian zones. (Thanks to Chris Walton.) In zone.tab, use more-precise coordinates for some Canadian locations. Commentary changes Many comments updated for planned changes in Canada next year. (Thanks to Chris Walton.) Add an official source for when Guatemalan DST is predicted to end this year. Add commentary about historical time zone boundaries within China. (Thanks to Jesper Norgaard Welen.) Add commentary suggesting that elements of the Australian government now seem to prefer time zone abbreviations like "AEST". (Thanks to Chuck Soper.) Clarify the statement of Mark Brader's findings on Toronto's DST in 1971. (Thanks to Mark Brader.) Remove commentary about this year's change in El Salvador, which didn't happen. Web page changes Revert from XHTML 1.0 to HTML 4.01. I was convinced by Ian Hickson's article "Sending XHTML as text/html Considered Harmful" <http://hixie.ch/advocacy/xhtml>. Maybe in a few years we can switch back to an XML-based approach. Oracle Database now uses the tz database. Update link to Time Zone Registry proposal, to point at calconnect.org. Add references to xmlDate, and to the Microsoft Windows Tzid table. Update reference to the Timezone Option to DHCP. Fix some HTML typos in tz-art.htm, and reformat some entries slightly. Add a pointer to John Dunning's book "Two O'Clock, Eastern Wartime". =================================================================== RCS file: RCS/Makefile,v retrieving revision 2006.9 retrieving revision 2006.9.0.1 diff -pu -r2006.9 -r2006.9.0.1 --- Makefile 2006/08/07 16:30:31 2006.9 +++ Makefile 2006/08/11 06:59:56 2006.9.0.1 @@ -223,16 +223,16 @@ ZIC= $(zic) $(ZFLAGS) AWK= nawk # The path where SGML DTDs are kept. -SGML_SEARCH_PATH= $(TOPDIR)/share/doc/sgml-lib/REC-xhtml1-20000126/ +SGML_SEARCH_PATH= $(TOPDIR)/share/doc/sgml-lib/REC-html401-19991224/ # The catalog file(s) to use when validating XHTML. -SGML_CATALOG_FILES= xhtml.soc +SGML_CATALOG_FILES= HTML4.cat # The name, arguments and environment of a program to validate your web pages. # See <http://www.jclark.com/sp/> for a validator, and # <http://validator.w3.org/source/> for a validation library.
