Import tzdata2013i from ftp://ftp.iana.org/tz/releases/tzdata2013i.tar.gz. 

Major changes from tzdata2013d to tzdata2013e:

  Fiji (Pacific/Fiji) DST in 2013 starts on October 27, not October 20.

  Several zones have been turned into links, either to correct errors,
  or where the differences were in older data (before 1943) that was
  thought to be unreliable.

  Some time zone abbreviations have been changed.

Major changes from tzdata2013e to tzdata2013f:

  Tocantins, Brazil (America/Araguaina) DST will not start in September
  2013.

  Jordan (Asia/Amman) moves to permanent UTC+3 (instead of UTC+2 with
  permanent DST since 2012).

  Palestine (Asia/Hebron and Asia/Gaza) will end DST at 00:00, not
  01:00, as from September 2013.

Major changes from tzdata2013f to tzdata2013g:

  Morocco (Africa/Casablanca) now observes DST from the last Sunday
  in March to the last Sunday in October, not April to September.
  respectively.

Major changes from tzdata2013g to tzdata2013h:

  Libya (Africa/Tripoli) has switched its time zone back to UTC+2
  without DST, instead of UTC+1 with DST.

  Western Sahara (Africa/El_Aaiun) uses Morocco's DST rules.

  Acre, Brazil (America/Rio_Branco) and (we guess) western Amazonas,
  Brazil (America/Eirunepe), will switch from UTC-4 to UTC-5 on
  2013-11-10.

  Add entries for DST transitions in Morocco in the year 2038.  This
  avoids some year-2038 glitches introduced in 2013g.

Major changes from tzdata2013h to tzdata2013i:

  Jordan (Asia/Amman) switches back to UTC+2 standard time at 00:00 on
  December 20, 2013.  The 2006-2011 DST transition schedule is planned
  to resume in 2014.  The switch to permanent UTC+3 is cancelled.

  In 2004, Cuba (America/Havana) began DST on March 28, not April 4.

  The files solar87, solar88, and solar89 are no longer distributed.
  The zones built from those files (Asia/Riyadh{87,88,89}) and
  Mideast/Riyadh{87,88,89}) are no longer installed.  They were a
  negative experiment -- that is, a demonstration that tz data can
  represent solar time only with some difficulty and error.  Their
  presence in the distribution caused confusion, as Riyadh civil time
  was generally not solar time in those years.

README for the tz distribution
"What time is it?" -- Richard Deacon as The King
"Any time you want it to be." -- Frank Baxter as The Scientist
(from the Bell System film "About Time")
The Time Zone Database (often called tz or zoneinfo) contains code and
data that represent the history of local time for many representative
locations around the globe. It is updated periodically to reflect
changes made by political bodies to time zone boundaries, UTC offsets,
and daylight-saving rules.
Unless otherwise specified, all files in the tz code and data are in
the public domain, so clarified as of 2009-05-17 by Arthur David Olson.
The few exceptions are code derived from BSD, which uses the BSD license.
Here is a recipe for acquiring, building, installing, and testing the
tz distribution on a GNU/Linux or similar host.
mkdir tz
cd tz
wget --retr-symlinks 'ftp://ftp.iana.org/tz/tz*-latest.tar.gz'
gzip -dc tzcode-latest.tar.gz | tar -xf -
gzip -dc tzdata-latest.tar.gz | tar -xf -
Be sure to read the comments in "Makefile" and make any changes needed
to make things right for your system, especially if you are using some
platform other than GNU/Linux. Then run the following commands,
substituting your desired installation directory for "$HOME/tzdir":
make TOPDIR=$HOME/tzdir install
$HOME/tzdir/etc/zdump -v America/Los_Angeles
Historical local time information has been included here to:
* provide a compendium of data about the history of civil time
that is useful even if the data are not 100% accurate;
* give an idea of the variety of local time rules that have
existed in the past and thus an idea of the variety that may be
expected in the future;
* provide a test of the generality of the local time rule description
system.
The information in the time zone data files is by no means authoritative;
the files currently do not even attempt to cover all time stamps before
1970, and there are undoubtedly errors even for time stamps since 1970.
If you know that the rules are different from those in a file, by all means
feel free to change a file (and please send the changed version to
tz@iana.org for use in the future). Europeans take note!
Thanks to these Timezone Caballeros who've made major contributions to the
time conversion package: Keith Bostic; Bob Devine; Paul Eggert; Robert Elz;
Guy Harris; Mark Horton; John Mackin; and Bradley White. Thanks also to
Michael Bloom, Art Neilson, Stephen Prince, John Sovereign, and Frank Wales
for testing work, and to Gwillim Law for checking local mean time data.
Thanks in particular to Arthur David Olson, the project's founder and first
maintainer, to whom the timezone community owes the greatest debt of all.
None of them are responsible for remaining errors.
Look in <ftp://ftp.iana.org/tz/releases/> for updated versions of these files.
Please send comments or information to tz@iana.org.

# falls entirely outside daylight-saving time; and with fall-back
# transitions removed for 2036-2037, where the normal fall-back
# date falls during the estimated Ramadan. Normally, the table would
# stop after 2037 because 32-bit time_t values roll around early in 2038,

#
# The following table shows the corrections that must
# be applied to compute International Atomic Time (TAI)
# from the Coordinated Universal Time (UTC) values that
# are transmitted by almost all time services.
#
# The first column shows an epoch as a number of seconds
# since 1900.0 and the second column shows the number of
# seconds that must be added to UTC to compute TAI for
# any timestamp at or after that epoch. The value on
# each line is valid from the indicated initial instant
# until the epoch given on the next one or indefinitely
# into the future if there is no next line.
# (The comment on each line shows the representation of
# the corresponding initial epoch in the usual
# day-month-year format. The epoch always begins at
# 00:00:00 UTC on the indicated day. See Note 5 below.)
#
# Important notes:
#
# 1. Coordinated Universal Time (UTC) is often referred to
# as Greenwich Mean Time (GMT). The GMT time scale is no
# longer used, and the use of GMT to designate UTC is
# discouraged.
#
# 2. The UTC time scale is realized by many national
# laboratories and timing centers. Each laboratory
# identifies its realization with its name: Thus
# UTC(NIST), UTC(USNO), etc. The differences among
# these different realizations are typically on the
# order of a few nanoseconds (i.e., 0.000 000 00x s)
# and can be ignored for many purposes. These differences
# are tabulated in Circular T, which is published monthly
# by the International Bureau of Weights and Measures
# (BIPM). See www.bipm.fr for more information.
#
# 3. The current defintion of the relationship between UTC
# and TAI dates from 1 January 1972. A number of different
# time scales were in use before than epoch, and it can be
# quite difficult to compute precise timestamps and time
# intervals in those "prehistoric" days. For more information,
# consult:
#
# The Explanatory Supplement to the Astronomical
# Ephemeris.
# or
# Terry Quinn, "The BIPM and the Accurate Measurement
# of Time," Proc. of the IEEE, Vol. 79, pp. 894-905,
# July, 1991.
#
# 4. The insertion of leap seconds into UTC is currently the
# responsibility of the International Earth Rotation Service,
# which is located at the Paris Observatory:
#
# Central Bureau of IERS
# 61, Avenue de l'Observatoire
# 75014 Paris, France.
#
# Leap seconds are announced by the IERS in its Bulletin C
#
# See hpiers.obspm.fr or www.iers.org for more details.
#
# All national laboratories and timing centers use the
# data from the BIPM and the IERS to construct their
# local realizations of UTC.
#
# Although the definition also includes the possibility
# of dropping seconds ("negative" leap seconds), this has
# never been done and is unlikely to be necessary in the
# foreseeable future.
#
# 5. If your system keeps time as the number of seconds since
# some epoch (e.g., NTP timestamps), then the algorithm for
# assigning a UTC time stamp to an event that happens during a positive
# leap second is not well defined. The official name of that leap
# second is 23:59:60, but there is no way of representing that time
# in these systems.
# Many systems of this type effectively stop the system clock for
# one second during the leap second and use a time that is equivalent
# to 23:59:59 UTC twice. For these systems, the corresponding TAI
# timestamp would be obtained by advancing to the next entry in the
# following table when the time equivalent to 23:59:59 UTC
# is used for the second time. Thus the leap second which
# occurred on 30 June 1972 at 23:59:59 UTC would have TAI
# timestamps computed as follows:
#
# ...
# 30 June 1972 23:59:59 (2287785599, first time): TAI= UTC + 10 seconds
# 30 June 1972 23:59:60 (2287785599,second time): TAI= UTC + 11 seconds
# 1 July 1972 00:00:00 (2287785600) TAI= UTC + 11 seconds
# ...
#
# If your system realizes the leap second by repeating 00:00:00 UTC twice
# (this is possible but not usual), then the advance to the next entry
# in the table must occur the second time that a time equivlent to
# 00:00:00 UTC is used. Thus, using the same example as above:
#
# ...
# 30 June 1972 23:59:59 (2287785599): TAI= UTC + 10 seconds
# 30 June 1972 23:59:60 (2287785600, first time): TAI= UTC + 10 seconds
# 1 July 1972 00:00:00 (2287785600,second time): TAI= UTC + 11 seconds
# ...
#
# in both cases the use of timestamps based on TAI produces a smooth
# time scale with no discontinuity in the time interval.
#
# This complexity would not be needed for negative leap seconds (if they
# are ever used). The UTC time would skip 23:59:59 and advance from
# 23:59:58 to 00:00:00 in that case. The TAI offset would decrease by
# 1 second at the same instant. This is a much easier situation to deal
# with, since the difficulty of unambiguously representing the epoch
# during the leap second does not arise.

# above, the update time (in NTP format) will be added to the basic
# file name leap-seconds to form the name leap-seconds.<NTP TIME>.
# In addition, the generic name leap-seconds.list will always point to
# the most recent version of the file.
#
# This update procedure will be performed only when a new leap second
# is announced.
#
# The following entry specifies the expiration date of the data
# in this file in units of seconds since 1900.0. This expiration date
# will be changed at least twice per year whether or not a new leap
# second is announced. These semi-annual changes will be made no
# later than 1 June and 1 December of each year to indicate what
# action (if any) is to be taken on 30 June and 31 December,
# respectively. (These are the customary effective dates for new
# leap seconds.) This expiration date will be identified by a
# unique pair of characters in columns 1 and 2 as shown below.
# In the unlikely event that a leap second is announced with an
# effective date other than 30 June or 31 December, then this
# file will be edited to include that leap second as soon as it is
# announced or at least one month before the effective date
# (whichever is later).
# If an announcement by the IERS specifies that no leap second is
# scheduled, then only the expiration date of the file will
# be advanced to show that the information in the file is still
# current -- the update time stamp, the data and the name of the file
# will not change.

# From Paul Eggert (2013-09-05):

# just say it's at UTC-3; see, for example,
# <http://es.wikipedia.org/wiki/Hora_oficial_argentina>.
# We've documented similar situations as being plain changes to
