Update to 2018f:

  Changes to code

    zic now always generates TZif files where time type 0 is used for
    timestamps before the first transition.  This simplifies the
    reading of TZif files and should not affect behavior of existing
    TZif readers because the same set of time types is used; only
    their internal indexes may have changed.  This affects only the
    legacy zones EST5EDT, CST6CDT, MST7MDT, PST8PDT, CET, MET, and
    EET, which previously used nonzero types for these timestamps.

    Because of the type 0 change, zic no longer outputs a dummy
    transition at time -2**59 (before the Big Bang), as clients should
    no longer need this to handle historical timestamps correctly.
    This reverts a change introduced in 2013d and shrinks most TZif
    files by a few bytes.

    zic now supports negative time-of-day in Rule and Leap lines, e.g.,
    "Rule X min max - Apr lastSun -6:00 1:00 -" means the transition
    occurs at 18:00 on the Saturday before the last Sunday in April.
    This behavior was documented in 2018a but the code did not
    entirely match the documentation.

    localtime.c no longer requires at least one time type in TZif
    files that lack transitions or have a POSIX-style TZ string.  This
    future-proofs the code against possible future extensions to the
    format that would allow TZif files with POSIX-style TZ strings and
    without transitions or time types.

    A read-access subscript error in localtime.c has been fixed.
    It could occur only in TZif files with timecnt == 0, something that
    does not happen in practice now but could happen in future versions.

    localtime.c no longer ignores TZif POSIX-style TZ strings that
    specify only standard time.  Instead, these TZ strings now
    override the default time type for timestamps after the last
    transition (or for all time stamps if there are no transitions),
    just as DST strings specifying DST have always done.

    leapseconds.awk now outputs "#updated" and "#expires" comments,
    and supports leap seconds at the ends of months other than June
    and December.  (Inspired by suggestions from Chris Woodbury.)

  Changes to documentation

    New restrictions: A Rule name must start with a character that
    is neither an ASCII digit nor "-" nor "+", and an unquoted name
    should not use characters in the set "!$%&'()*,/:;<=>?@[\]^`{|}~".
    The latter restriction makes room for future extensions (a
    possibility noted by Tom Lane).

    tzfile.5 now documents what time types apply before the first and
    after the last transition, if any.

    Documentation now uses the spelling "timezone" for a TZ setting
    that determines timestamp history, and "time zone" for a
    geographic region currently sharing the same standard time.

    The name "TZif" is now used for the tz binary data format.

    tz-link.htm now mentions the A0 TimeZone Migration utilities.
    (Thanks to Aldrin Martoq for the link.)

Merge 2018e

  Changes to code

    zic now accepts subsecond precision in expressions like
    00:19:32.13, which is approximately the legal time of the
    Netherlands from 1835 to 1937.  However, because it is
    questionable whether the few recorded uses of non-integer offsets
    had subsecond precision in practice, there are no plans for tzdata
    to use this feature.  (Thanks to Steve Allen for pointing out
    the limitations of historical data in this area.)

    The code is a bit more portable to MS-Windows.  Installers can
    compile with -DRESERVE_STD_EXT_IDS on MS-Windows platforms that
    reserve identifiers like 'localtime'.  (Thanks to Manuela
    Friedrich).

  Changes to documentation and commentary

    theory.html now outlines tzdb's extensions to POSIX's model for
    civil time, and has a section "POSIX features no longer needed"
    that lists POSIX API components that are now vestigial.
    (From suggestions by Steve Summit.)  It also better distinguishes
    time zones from tz regions.  (From a suggestion by Guy Harris.)

    Commentary is now more consistent about using the phrase "daylight
    saving time", to match the C name tm_isdst.  Daylight saving time
    need not occur in summer, and need not have a positive offset from
    standard time.

    Commentary about historical transitions in Uruguay has been expanded
    with links to many relevant legal documents.
    (Thanks to Tim Parenti.)

    Commentary now uses some non-ASCII characters with Unicode value
    less than U+0100, as they can be useful and should work even with
    older editors such as XEmacs.

Merge tzcode2018c [ changelog with changes to tzdata sections removed ]

Release 2018c - 2018-01-22 23:00:44 -0800

  Changes to build procedure

    The build procedure now works around mawk 1.3.3's lack of support
    for character class expressions.  (Problem reported by Ohyama.)


Release 2018b - 2018-01-17 23:24:48 -0800

  Changes to build procedure

    The distribution now contains the file 'pacificnew' again.
    This file was inadvertantly omitted in the 2018a distribution.
    (Problem reported by Matias Fonzo.)


Release 2018a - 2018-01-12 22:29:21 -0800

  Changes to build procedure

    The default installation locations have been changed to mostly
    match Debian circa 2017, instead of being designed as an add-on to
    4.3BSD circa 1986.  This affects the Makefile macros TOPDIR,
    TZDIR, MANDIR, and LIBDIR.  New Makefile macros TZDEFAULT, USRDIR,
    USRSHAREDIR, BINDIR, ZDUMPDIR, and ZICDIR let installers tailor
    locations more precisely.  (This responds to suggestions from
    Brian Inglis and from Steve Summit.)

    The default installation procedure no longer creates the
    backward-compatibility link US/Pacific-New, which causes
    confusion during user setup (e.g., see Debian bug 815200).
    Use 'make BACKWARD="backward pacificnew"' to create the link
    anyway, for now.  Eventually we plan to remove the link entirely.

    tzdata.zi now contains a version-number comment.
    (Suggested by Tom Lane.)

    The Makefile now quotes values like BACKWARD more carefully when
    passing them to the shell.  (Problem reported by Zefram.)

    Builders no longer need to specify -DHAVE_SNPRINTF on platforms
    that have snprintf and use pre-C99 compilers.  (Problem reported
    by Jon Skeet.)

  Changes to code

    zic has a new option -t FILE that specifies the location of the
    file that determines local time when TZ is unset.  The default for
    this location can be configured via the new TZDEFAULT makefile
    macro, which defaults to /etc/localtime.

    Diagnostics and commentary now distinguish UT from UTC more
    carefully; see theory.html for more information about UT vs UTC.

    zic has been ported to GCC 8's -Wstringop-truncation option.
    (Problem reported by Martin Sebor.)

  Changes to documentation and commentary

    The zic man page now documents the longstanding behavior that
    times and years can be out of the usual range, with negative times
    counting backwards from midnight and with year 0 preceding year 1.
    (Problem reported by Michael Deckers.)

    The theory.html file now mentions the POSIX limit of six chars
    per abbreviation, and lists alphabetic abbreviations used.

    The files tz-art.htm and tz-link.htm have been renamed to
    tz-art.html and tz-link.html, respectively, for consistency with
    other file names and to simplify web server configuration.

Welcome to 2017c:

    zic and the reference runtime now reject multiple leap seconds
    within 28 days of each other, or leap seconds before the Epoch.
    As a result, support for double leap seconds, which was
    obsolescent and undocumented, has been removed.  Double leap
    seconds were an error in the C89 standard; they have never existed
    in civil timekeeping.  (Thanks to Robert Elz and Bradley White for
    noticing glitches in the code that uncovered this problem.)

    zic now warns about use of the obsolescent and undocumented -y
    option, and about use of the obsolescent TYPE field of Rule lines.

    zic now allows unambiguous abbreviations like "Sa" and "Su" for
    weekdays; formerly it rejected them due to a bug.  Conversely, zic
    no longer considers non-prefixes to be abbreviations; for example,
    it no longer accepts "lF" as an abbreviation for "lastFriday".
    Also, zic warns about the undocumented usage with a "last-"
    prefix, e.g., "last-Fri".

    Similarly, zic now accepts the unambiguous abbreviation "L" for
    "Link" in ordinary context and for "Leap" in leap-second context.
    Conversely, zic no longer accepts non-prefixes such as "La" as
    abbreviations for words like "Leap".

    zic no longer accepts leap second lines in ordinary input, or
    ordinary lines in leap second input.  Formerly, zic sometimes
    warned about this undocumented usage and handled it incorrectly.

    The new macro HAVE_TZNAME governs whether the tzname external
    variable is exported, instead of USG_COMPAT.  USG_COMPAT now
    governs only the external variables "timezone" and "daylight".
    This change is needed because the three variables are not in the
    same category: although POSIX requires tzname, it specifies the
    other two variables as optional.  Also, USG_COMPAT is now 1 or 0:
    if not defined, the code attempts to guess it from other macros.

    localtime.c and difftime.c no longer require stdio.h, and .c files
    other than zic.c no longer require sys/wait.h.

    zdump.c no longer assumes snprintf.  (Reported by Jonathan Leffler.)

    Calculation of time_t extrema works around a bug in GCC 4.8.4
    (Reported by Stan Shebs and Joseph Myers.)

    zic.c no longer mistranslates formats of line numbers in non-English
    locales.  (Problem reported by Benno Schulenberg.)

    Several minor changes have been made to the code to make it a
    bit easier to port to MS-Windows and Solaris.  (Thanks to Kees
    Dekker for reporting the problems.)

  Changes to documentation and commentary

    The two new files 'theory.html' and 'calendars' contain the
    contents of the removed file 'Theory'.  The goal is to document
    tzdb theory more accessibly.

    The zic man page now documents abbreviation rules.

    tz-link.htm now covers how to apply tzdata changes to clients.
    (Thanks to Jorge Fábregas for the AIX link.)  It also mentions MySQL.

    The leap-seconds.list URL has been updated to something that is
    more reliable for tzdb.  (Thanks to Tim Parenti and Brian Inglis.)

    (Thanks to Theo Veenker for reporting the problem, for MinGW.)
    Also, fix some bugs on platforms that lack hard links but have symlinks.

    'zic -v' again warns that Asia/Tehran has no POSIX environment variable
    to predict the far future, fixing a bug introduced in 2013e.
f:
    The types of the global variables 'timezone' and 'altzone' (if present)
    have been changed back to 'long'.  This is required for 'timezone'
    by POSIX, and for 'altzone' by common practice, e.g., Solaris 11.
    These variables were originally 'long' in the tz code, but were
    mistakenly changed to 'time_t' in 1987; nobody reported the
    incompatibility until now.  The difference matters on x32, where
    'long' is 32 bits and 'time_t' is 64.  (Thanks to Elliott Hughes.)

Welcome to tzcode 2013e:

  Changes affecting API

    The 'zic' command now outputs a dummy transition when far-future
    data can't be summarized using a TZ string, and uses a 402-year
    window rather than a 400-year window.  For the current data, this
    affects only the Asia/Tehran file.  It does not affect any of the
    time stamps that this file represents, so zdump outputs the same
    information as before.  (Thanks to Andrew Main (Zefram).)

    The 'date' command has a new '-r' option, which lets you specify
    the integer time to display, a la FreeBSD.

    The 'tzselect' command has two new options '-c' and '-n', which lets you
    select a zone based on latitude and longitude.

    The 'zic' command's '-v' option now warns about constructs that
    require the new version-3 binary file format.  (Thanks to Arthur
    David Olson for the suggestion.)

    Support for floating-point time_t has been removed.
    It was always dicey, and POSIX no longer requires it.
    (Thanks to Eric Blake for suggesting to the POSIX committee to
    remove it, and thanks to Alan Barrett, Clive D.W. Feather, Andy
    Heninger, Arthur David Olson, and Alois Treindl, for reporting
    bugs and elucidating some of the corners of the old floating-point
    implementation.)

    The signatures of 'offtime', 'timeoff', and 'gtime' have been
    changed back to the old practice of using 'long' to represent UT
    offsets.  This had been inadvertently and mistakenly changed to
    'int_fast32_t'.  (Thanks to Christos Zoulos.)

    The code avoids undefined behavior on integer overflow in some
    more places, including gmtime, localtime, mktime and zdump.

  Changes affecting the zdump utility

    zdump now outputs "UT" when referring to Universal Time, not "UTC".
    "UTC" does not make sense for time stamps that predate the introduction
    of UTC, whereas "UT", a more-generic term, does.  (Thanks to Steve Allen
    for clarifying UT vs UTC.)

  Data changes affecting behavior of tzselect and similar programs

    Country code BQ is now called the more-common name "Caribbean Netherlands"
    rather than the more-official "Bonaire, St Eustatius & Saba".

    Remove from zone.tab the names America/Montreal, America/Shiprock,
    and Antarctica/South_Pole, as they are equivalent to existing
    same-country-code zones for post-1970 time stamps.  The data for
    these names are unchanged, so the names continue to work as before.

  Changes affecting code internals

    zic -c now runs way faster on 64-bit hosts when given large numbers.

    zic now uses vfprintf to avoid allocating and freeing some memory.

    tzselect now computes the list of continents from the data,
    rather than have it hard-coded.

    Minor changes pacify GCC 4.7.3 and GCC 4.8.1.

  Changes affecting the build procedure

    The 'leapseconds' file is now generated automatically from a
    new file 'leap-seconds.list', which is a copy of
    <ftp://time.nist.gov/pub/leap-seconds.list>.
    A new source file 'leapseconds.awk' implements this.
    The goal is simplification of the future maintenance of 'leapseconds'.

    When building the 'posix' or 'right' subdirectories, if the
    subdirectory would be a copy of the default subdirectory, it is
    now made a symbolic link if that is supported.  This saves about
    2 MB of file system space.

    The links America/Shiprock and Antarctica/South_Pole have been
    moved to the 'backward' file.  This affects only nondefault builds
    that omit 'backward'.

  Changes affecting documentation and commentary

    Changes to the 'tzfile' man page

      It now mentions that the binary file format may be extended in
      future versions by appending data.

      It now refers to the 'zdump' and 'zic' man pages.

    Changes to the 'zic' man page

      It lists conditions that elicit a warning with '-v'.

      It says that the behavior is unspecified when duplicate names
      are given, or if the source of one link is the target of another.

      Its examples are updated to match the latest data.

      The definition of white space has been clarified slightly.
      (Thanks to Michael Deckers.)

    Changes to the 'Theory' file

      There is a new section about the accuracy of the tz database,
      describing the many ways that errors can creep in, and
      explaining why so many of the pre-1970 time stamps are wrong or
      misleading (thanks to Steve Allen, Lester Caine, and Garrett
      Wollman for discussions that contributed to this).

      The 'Theory' file describes LMT better (this follows a
      suggestion by Guy Harris).

      It refers to the 2013 edition of POSIX rather than the 2004 edition.

      It's mentioned that excluding 'backward' should not affect the
      other data, and it suggests at least one zone.tab name per
      inhabited country (thanks to Stephen Colebourne).

      Some longstanding restrictions on names are documented, e.g.,
      'America/New_York' precludes 'America/New_York/Bronx'.

      It gives more reasons for the 1970 cutoff.

      It now mentions which time_t variants are supported, such as
      signed integer time_t.  (Thanks to Paul Goyette for reporting
      typos in an experimental version of this change.)

      (Thanks to Philip Newton for correcting typos in these changes.)

    Documentation and commentary is more careful to distinguish UT in
    general from UTC in particular.  (Thanks to Steve Allen.)

    Add a better source for the Zurich 1894 transition.
    (Thanks to Pierre-Yves Berger.)

    Update shapefile citations in tz-link.htm.  (Thanks to Guy Harris.)
