Time Zone Distribution Protocol WG Milestones (tzdist)
by Daniel Migault Aug. 13, 2014

Aug. 13, 2014

Hi, We are getting under way with the tzdist WG <http://datatracker.ietf.org/wg/tzdist/charter/> [1]. This IETF working group (WG) goal is to define time zone data distribution protocols. If you want to join please the tzdist WG <https://www.ietf.org/mailman/listinfo/tzdist> [2]. These are the milestones we propose. If you have any comments, please feel free to post them before Tuesday August 19 so we can consider them. Milestones: - September 2014 Adopt time zone data distribution protocol draft as WG document - September 2014 Adopt an CalDAV extension draft as WG document - January 2015 Submit time zone data distribution protocol draft for WGLC - March 2015 Submit time zone data distribution protocol draft as Standards Track RFC - March 2015 Submit CalDAV extension draft for WGLC - June 2015 Submit CalDAV extension draft as Standards Track RFC - September 2016 re-charter the WG [1] http://datatracker.ietf.org/wg/tzdist/charter/ [2] https://www.ietf.org/mailman/listinfo/tzdist -- Daniel Migault Orange Labs -- Security +33 6 70 72 69 58

Before 1970 - proposal to change LMT
by Stephen Colebourne Aug. 11, 2014

Aug. 11, 2014

The TZDB has few issues after 1970 as far as I can see, but before that date there are debates about what should be included and what should not. Options include - nothing at all before 1970 (but the format demands something...) - only data that has some reasonable source before 1970 - include data before 1970 even if its source is less than ideal Ultimately, the problem revolves around the data format (which cannot realistically be changed) and LMT. In the past there have been various discussions around LMT with the conclusion that it is a bit of a silly concept, because it refers to a single location, not a region. But we are in the position where the format requires it, and it is widely used (even if that use is accidental rather than deliberate). Broadly, my position is that where data can be verified pre-1970, such as in the UK, or my recent Angola email, it should be retained. Commentary should be added to the data files to justify the data that is present. Where the data cannot be verified, I am willing to take a judgement call, provided that the judgement call is not just "we don't know so lets link it elsewhere". What I find objectionable is to have a named entity (zone or link) where the LMT of the named location is replaced by the LMT of some other location. I understand that others may not care, but it seems flat out wrong to me (and is key to solving the pre-1970 problem). Therefore, I'd like to propose a simple alteration to LMT. I propose that all LMT values in the database are replaced by an new value, representing what could be described as "averaged/smoothed regional far past time". In real terms, this means changing all the LMT values to an appropriate fixed value for that location. Once the fixed value is chosen, there should be no reason not to retain it forever. The intention is that the fixed offset value is the most common standard offset used by the location, favouring an offset close to the LMT if ambiguous. The offset chosen would typically be a multiple of 15 minutes, and not contain seconds at all. To help frame the debate, I produced a list of zones and all their *standard* transitions (excluding DST) for 2013h; https://gist.github.com/jodastephen/03487c61782e612db85d Some examples: Europe/London -00:01:15 LMT Z 1847-12-01 My proposal is to change the LMT value from "-00:01:15" to "Z" America/New_York -04:56:02 -05:00 1883-11-18 My proposal is to change the LMT value from "-04:56:02" to "-05:00" America/Panama -05:18:08 -05:19:36 1890-01-01 -05:00 1908-04-22 My proposal is to change the LMT value from "-05:18:08" to "-05:00". If justification for the "-05:19:36" value cannot be found, then that should be removed. The net effect of this would be to provide a much more regularized value for the far past (pre 1850 or later). In most cases, the new LMT offset would be the same as the first non-LMT offset, resulting in the removal of a messy transition, leaving only a name change (eg LMT to GMT). Advantages - regularized far past (my experience shows that developers find the LMT seconds offset confusing when they see it) - increased stability, once adopted there is no reason for the LMT value to change - minimizes churn in the database due to "more accurate" longitude/latitude - allows the same offset to be used even if the largest city changes in a region - typically aligns the far past with the first "real" zone definition line - allows multiple locations to be linked (as per recent changes) without debate about changing any timestamps in most cases - when multiple locations are linked, only the start of regular time is then significant data (where known it should be retained) Disadvantages: - changes the meaning of LMT (the name could be possibly be changed to FPT - far past time) - loses existing LMT data (it could still be made available in a separate file) - requires a one-off change I hope that this proposal can be considered, as it would seem to address the majority of the issues in a simple and neat way that benefits most downstream consumers with extra regularity and stability.

[PATCH] New file time.tab, superseding zone.tab
by Paul Eggert Aug. 11, 2014

Aug. 11, 2014

It allows multiple country codes per zone. Switch code and data to use the new format, along with the recently-added Crozet Islands entry. The old zone.tab file is still installed but is deprecated. The new file uses UTF-8; add commentary saying that iso3166.tab is planned to change to UTF-8. * Theory, tzselect.8 (FILES): zone.tab -> time.tab. * africa (Indian/Alfred_Faure): Remove link. * antarctica: Mention Possession Island in comments. * checktab.awk: Add support for checking time.tab. * iso3166.tab: Mention planned switch to UTF-8. Update ISO 3166-1 Newsletter from VI-15 to VI-16. * time.tab: New file. * tzselect.ksh (zonetabtype): New variable. Add undocumented -t option, meant for developer testing. (TZ_ZONE_TABLE): Use zonetabtype. (output_distances, countries, regions, TZ): Support time.tab format. (quoted_continents, distance_table, countries, regions) (TZ, TZ_for_date): Quote shell strings more carefully. * zone.tab: Refer to time.tab for detailed comments about format. (Indian/Alfred_Faure): Remove. * Makefile (TIMETABLES): New macro. (TABDATA, install, check_tables): Use it. (check_character_set, check_tables): Check time.tab too. (check_time_t_alternatives): Use time.tab, not zone.tab. * NEWS: Document the above. --- Makefile | 20 ++-- NEWS | 15 ++- Theory | 4 +- africa | 3 +- antarctica | 2 +- checktab.awk | 58 +++++----- iso3166.tab | 12 +- time.tab | 371 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ tzselect.8 | 4 +- tzselect.ksh | 35 ++++-- zone.tab | 37 ++---- 11 files changed, 477 insertions(+), 84 deletions(-) create mode 100644 time.tab diff --git a/Makefile b/Makefile index 8de640a..68388b3 100644 --- a/Makefile +++ b/Makefile @@ -340,7 +340,8 @@ PRIMARY_YDATA= africa antarctica asia australasia \ YDATA= $(PRIMARY_YDATA) pacificnew etcetera backward NDATA= systemv factory TDATA= $(YDATA) $(NDATA) -TABDATA= iso3166.tab zone.tab leapseconds +TIMETABLES= time.tab zone.tab +TABDATA= iso3166.tab $(TIMETABLES) leapseconds LEAP_DEPS= leapseconds.awk leap-seconds.list DATA= $(YDATA) $(NDATA) $(TABDATA) \ $(LEAP_DEPS) yearistype.sh @@ -364,7 +365,7 @@ install: all $(DATA) $(REDO) $(MANS) $(DESTDIR)$(MANDIR)/man8 $(ZIC) -y $(YEARISTYPE) \ -d $(DESTDIR)$(TZDIR) -l $(LOCALTIME) -p $(POSIXRULES) - cp -f iso3166.tab zone.tab $(DESTDIR)$(TZDIR)/. + cp -f iso3166.tab $(TIMETABLES) $(DESTDIR)$(TZDIR)/. cp tzselect zic zdump $(DESTDIR)$(ETCDIR)/. cp libtz.a $(DESTDIR)$(LIBDIR)/. $(RANLIB) $(DESTDIR)$(LIBDIR)/libtz.a @@ -455,13 +456,18 @@ check_character_set: $(ENCHILADA) sharp='#' && \ ! grep -Env $(SAFE_LINE) $(MANS) date.1 $(MANTXTS) \ $(MISC) $(SOURCES) $(WEB_PAGES) && \ - ! grep -Env $(SAFE_SHARP_LINE) $(DATA) && \ + ! grep -Env $(SAFE_SHARP_LINE) $(YDATA) $(NDATA) iso3166.tab \ + zone.tab leapseconds $(LEAP_DEPS) yearistype.sh && \ test $$(grep -Ecv $(SAFE_SHARP_LINE) Makefile) -eq 1 && \ - ! grep -Env $(NONSYM_LINE) README NEWS Theory $(MANS) date.1 && \ + ! grep -Env $(NONSYM_LINE) README NEWS Theory $(MANS) date.1 \ + time.tab && \ ! grep -Env $(VALID_LINE) $(ENCHILADA) -check_tables: checktab.awk $(PRIMARY_YDATA) - $(AWK) -f checktab.awk $(PRIMARY_YDATA) +check_tables: checktab.awk $(PRIMARY_YDATA) $(TIMETABLES) + for tab in $(TIMETABLES); do \ + $(AWK) -f checktab.awk -v zone_table=$$tab $(PRIMARY_YDATA) \ + || exit; \ + done check_web: $(WEB_PAGES) $(VALIDATE_ENV) $(VALIDATE) $(VALIDATE_FLAGS) $(WEB_PAGES) @@ -540,7 +546,7 @@ check_public: $(ENCHILADA) # Check that the code works under various alternative # implementations of time_t. check_time_t_alternatives: - zones=`$(AWK) '/^[^#]/ { print $$3 }' <zone.tab` && \ + zones=`$(AWK) '/^[^#]/ { print $$3 }' <time.tab` && \ for type in $(TIME_T_ALTERNATIVES); do \ mkdir -p tzpublic/$$type && \ make clean_misc && \ diff --git a/NEWS b/NEWS index ffcbd92..babfdac 100644 --- a/NEWS +++ b/NEWS @@ -120,11 +120,22 @@ Unreleased, experimental changes Europe/Riga.

Proposed update to tz-link.htm for Microsoft Windows
by Matt Johnson Aug. 11, 2014

Aug. 11, 2014

Please find attached a patch which contains more specific information about time zone support in Microsoft Windows. In particular, I'm correcting the previous information which stated that the Windows time zone format was undocumented. I've provided links to all of the relevant documentation. I've also clarified the use of TZ data in the new Windows Runtime APIs. The previous text made it sound like DateTimeFormatter can perform CLDR conversions, which it cannot. Please let me know if there are any suggested revisions. Thanks, Matt

Have brought my tzdata clone up to date, and re-merged the new data. http://hg.lsces.org.uk/hg/tzdata/rev/c8017bbdb194 In the process of checking things, I found a few broken links in the europe file http://hg.lsces.org.uk/hg/tz/rev/f998f498222b Have several extra links to go with Joseph's UK details as well ... A lot of the material has now been scanned and is on-line. -- Lester Caine - G8HFL ----------------------------- Contact - http://lsces.co.uk/wiki/?page=contact L.S.Caine Electronic Services - http://lsces.co.uk EnquirySolve - http://enquirysolve.com/ Model Engineers Digital Workshop - http://medw.co.uk Rainbow Digital Media - http://rainbowdigitalmedia.co.uk
