Different tzdata-latest.tar.gz files returned from different servers
by David Kyes Oct. 20, 2015

Oct. 20, 2015

Hello, It appears cache1.lax.icann.org is still returning the previous 2015f tzdata file when requesting the tzdata-latest.tar.gz from www.iana.org. I have been receiving 2 different responses for the tzdata-latest.tar.gz depending on which icann.org server handles the request. cache1.lax.icann.org is responding with the 2015f tzdata file and "cache1.lax.icann.org" is returning the 2015g. Below are network traces which show the difference in X-Cache-Host , Content-Length and Last-Modified response headers. Opening the Makefile confirms the different versions.

question about SHA512 when using tzdata
by gerar.moisset＠orange.com Oct. 19, 2015

Oct. 19, 2015

Hello. Is it possible to have a howto procedure ot use SHA-512 checksums when using tzdata? I am getting some errors when trying to update our java, like this, /opt/jdksun64/1.7.0_71/bin/java -jar /opt/jdksun64/1.7.0_71/jre/lib/tzupdater.jar -f -l http://localhost:81/tzdata2015g.tar.gz -v It returns, tzupdater tool would update with tzdata version: tzdata2015g Error encountered while downloading https://javadl-esd-secure.oracle.com/update/tzupdater/tzdata2015g.tar.gz.sh… And I don't see very well how to use your SHA-512 checksums procedure.

Bloomberg open-source tzdata implementation
by Andrew Paprocki Oct. 16, 2015

Oct. 16, 2015

For anyone interested, a new implementation was recently open-sourced. Bloomberg's timezone library including tzdata parser was part of the recent 3.0 release of the BDE C++ library. This is built on top of the previously released date/time vocabulary types. High-level utility for performing conversions, TimeZoneUtil (doxygen): http://bloomberg.github.io/bde/group__baltzo__timezoneutil.html All baltzo:: component docs: http://bloomberg.github.io/bde/group__baltzo.html All baltzo:: component code: https://github.com/bloomberg/bde/blob/master/groups/bal/baltzo -Andrew @ Bloomberg

Europe/Jersey and Europe/Guernsey did not follow London during the war and other backzone aliases also vary across Europe in that period Europe/Belfast followed Ireland pre 1968 and like Europe/Isle_of_Man switched to a standard time at a different date to the rest of the UK. All only little point's, but important differences in the pre 1970 chronology! These differences are validated data ... but missing if a distribution simply switches backzone off and while yes some backzone material is unverified, this particular section is very much verified. So how does one recognise that those aliases are returning the correct pre-1970 data and not just mirroring Europe/London or one of the other generic European rule sets? -- 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

Timezone in Brazil
by MARCIO IKEDA Oct. 11, 2015

Oct. 11, 2015

This is Marcio Ikeda from LG Electronics in Brazil. Nice to meet you! I would like to know if there are some background history for timezones in Brazil. It seems that Brasilia city which is the capital, is only treated as a metaZone and not a timeZone. I would like to know if are there some discussions on why America/Brasilia is not in the list. And if It is possible to include it. This is causing people from QA here to question this. Thank you!

Not sure if this casts light or mud on the issue, but last year (Feb '14) I contacted a business on Isla Cedros (which is in Baja) about the local time, and received this reply (relevant passage underscored): >Mr Jones >Thank you for coming to us for the answer. >Cedros island is governed by the Baja California State, therefore >most of the time it has the same time zone Pacific shared by >California.

Re: [tz] America/Santa_Isabel

The use of Santa Isabel does indeed seem to be an error. I see, though, that San Felipe, like Santa Isabel, is part of the Mexicali municipality; San Felipe may also use U. S. rules. The "northamerica" file's quotation of the relevant decree mentions "los municipios de Tijuana y Mexicali" but only "la Ciudad de Ensenada" (rather than "el municipio"); we may get to use the largest city in the Ensenada municipality that's south of the city of Ensenada. That seems to be Rodolfo Sánchez Taboada (Maneadero) (22,957); the normal 14-character limit would suggest using Maneadero; it seems to have a larger population that San Felipe (16,702). Lázaro Cárdenas (16,294) is substantially farther south and thus likelier to use Mexican rules; some 14-character-limit creativity would be required. Of course if we were lucky we'd discover that Santa Isabel actually uses Mexican rules.-S --ado https://en.wikipedia.org/wiki/San_Felipe,_Baja_California https://en.wikipedia.org/wiki/Ensenada_Municipality

America/Santa_Isabel
by Matt Johnson Oct. 8, 2015

Oct. 8, 2015

Does anyone know why America/Santa_Isabel was chosen to represent the portion of Baja California (Mexico) that follows Mexican DST rules? Santa Isabel is just as close to the US border as Tijuana and Mexicali, which are in the America/Tijuana zone. According to Wikipedia ( https://en.wikipedia.org/wiki/Baja_California ) "Over 75% of the population lives in the capital city, Mexicali, in Ensenada, or in Tijuana. Other important cities include San Felipe, Rosarito and Tecate." Of those, it would seem Ensenda and San Felipe would be the only cities not near the US border, and my understanding is that Ensenada follows the US rules. Wouldn't then America/San_Felipe be a better choice?
