[tz] ICANN contacts Egyptian government about recent last-minute clock change

Baher Esmat of ICANN contacted the Egyptian government asking it to give 
us more notice about clock changes next time. This found its way into 
the popular press earlier this month; here's the English-language version:

[tz] Google search results displaying wrong time for Egypt

If you search for "current time in Egypt" (at least for me in NYC), it will display a UTC+3 time as if DST was applied (tzdata2016f not being used).

In case there are any Googlers on the list want to raise awareness internally...

Re: [tz] Joda-Time, Time4J, and Java SE 8

Thanks for the correction. Sorry, I don't know Joda-Time vs Java SE 8 vs 
Time4J well.

I'm trying to future-proof tz-link.htm. As I understand it from the 
Joda-Time web page, Joda-Time-using apps are expected to migrate to the 
Java SE 8 API, so future readers of tz-link.htm will mostly be using the 
Java API, with more-specialized uses (leap seconds? sorry, don't know 
the details) possibly using Time4J, and Joda-Time being a historical 
footnote.

I installed the attached further patch into the experimental tz version 
on GitHub; I hope it addresses this point well enough. I'll CC: Stephen 
Colebourne to give him a heads-up, as I do want tz-link.htm to be accurate.

[tz] Fwd: tzcode: system-dependent default time zone file

[Belated reply to an earlier thread.  Feel free to post this to
the tz list, or not, your choice.  Other than Guy Harris, I don't
know how interested the rest of the list is in these lower-level
coding and build details.]

Back in January, in the "tzcode test suite" thread, Paul and I
had this exchange:

>> I'm not sure what that warning about "no nontrivial tz offset tested"
>> means, but I hope we can fix the testsuite to set TZ itself if that's

I believe the problem is simply some variation across systems in
the location of the tz file that sets a machine's local time zone
in the absence of a TZ environment variable.  As compiled out of
the box, tzcode expects to find this in TZDIR/localtime, that is,
in /usr/share/zoneinfo/localtime.  But on my Mac it's /etc/localtime,
and I suspect it's probably there on Paul's Fedora machine, too.

The fix is simple: I'm now setting

	TZDEFAULT = "/etc/localtime"

in the Makefile, and then passing it down to the compilations:

	CC = $(cc) -DTZDIR=\"$(TZDIR)\" -DTZDEFAULT=\"$(TZDEFAULT)\"

With these changes, I no longer need to explicitly set TZ to keep
tzcode's copy of localtime happy.

I was going to propose adding this comment to the Makefile in the
tz distribution:

	# By default, the local time zone is taken from the file
	# "localtime" in TZDIR.  Or you can set TZDEFAULT to something
	# else (for example, it's typically "/etc/localtime" for MacOS,
	# BSD, and some versions of Linux).

But I believe TZDEFAULT in the same Makefile is also used when
*installing* a set of zoneinfo files built from tzdata, and I'm
uncertain of the repercussions for tzdata builds if I encourage
people to tinker with TZDEFAULT to match their OS.

This is probably a symptom of a deeper issue: if someone
downloads and builds tzdata and/or tzcode, is it assumed that
they'll be installing and referencing the zoneinfo files in the
tzdata/tzcode default location, or in their OS's preferred
location, or what?  And the answer gets more complicated
depending on whether people are actually using tzcode, or their
OS's possibly different tz code -- glibc or whatever -- instead.

[tz] New leap second

Dear users of tzdb,

IERS has announced a new leap second at the end of year 2016, see

https://hpiers.obspm.fr/iers/bul/bulc/bulletinc.dat

Another point:

I have myself written a time library in Java called Time4J which contains a tz compiler based on your data and which also evaluates the leap second file contained in tz-data. Hence this library could be listed in the file "tz-link" within the section "Other tz compilers" maybe with this description:

<a href="https://github.com/MenoData/Time4J/">Time4J &ndash; Advanced date, time and interval library for Java</a> , uses the class
<code>net.time4j.tool.TimezoneRepositoryCompiler.java</code> located in TZTool-module that compiles
<code><abbr>tz</abbr></code> source into a Time4J-specific binary format.  Time4J is available under a LGPLv2.1-licence.

Cheers and thanks for your very useful work

[tz] [tz-announce] 2016f release of tz code and data available

The 2016f release of the tz code and data is available. It reflects the 
following changes, which were either circulated on the tz mailing list 
or are relatively minor technical or administrative changes:

   Changes affecting future time stamps

     The Egyptian government changed its mind on short notice, and
     Africa/Cairo will not introduce DST starting 2016-07-07 after all.
     (Thanks to Mina Samuel.)

     Asia/Novosibirsk switches from +06 to +07 on 2016-07-24 at 02:00.
     (Thanks to Stepan Golosunov.)

   Changes to past and future time stamps

     Asia/Novokuznetsk and Asia/Novosibirsk now use numeric time zone
     abbreviations instead of invented ones.

   Changes affecting past time stamps

     Europe/Minsk's 1992-03-29 spring-forward transition was at 02:00 
not 00:00.
     (Thanks to Stepan Golosunov.)
