proposed time zone package changes (Samoa, Factory, et al.)
by Arthur David Olson Aug. 28, 2019

Aug. 28, 2019

Below find proposed time zone package changes; the executive summary: * Makefile Change LOCALTIME default from "Factory" to "GMT"; do not compile "factory" file (but keep it in the distribution). * Theory Remove reference to "Factory" zone. * australasia Change end of DST in Samoa in 2011 from 2011-04-03 0:00 to 2011-04-03 1:00 (thanks to Raymond Hughes for a reference). * localtime.c Initialize ttinfo structures filled by tzparse (thanks to Ravindra for reporting a valgrind warning). * zic.c Fix generation of POSIX strings for zones with rules using "weekday<=n" forms of dates (thanks to Lei Liu for finding the problem). Also, limit output for non-POSIX-specificable zones defined to follow the same rules every year. (Note that no zones of either of the above types appear in the distribution; these changes cater to add-on zones). If no problems are found, 2010n will appear on 2010-10-25. --ado diff -r -c old/Makefile new/Makefile *** old/Makefile Mon Sep 27 09:24:25 2010 --- new/Makefile Tue Oct 12 12:36:50 2010 *************** *** 1,5 **** # <pre> ! # @(#)Makefile 8.8 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. --- 1,5 ---- # <pre> ! # @(#)Makefile 8.9 # This file is in the public domain, so clarified as of # 2009-05-17 by Arthur David Olson. *************** *** 12,18 **** # make zonenames # to get a list of the values you can use for LOCALTIME. !

Adding Asia/Beijing timezone into the database
by Daoming Qiu Dec. 6, 2014

Dec. 6, 2014

"Beijing Time" is the standard time used for China region, so it is very strange that tzdatabase doesn't have timezone called Asia/Beijing. Strongly suggest to add "Asia/Beijing" zone into the database, and its information is very similar with "Asia/Shanghai".

a patch for zic.c to allow 'follow rules'
by Alois Treindl Sept. 10, 2013

Sept. 10, 2013

Dear Arthur, I have been preparing a small modification for zic.c which will allow it to understand a 'follow rule' in zone files, like this: # experimental table for Geneva, to test the 'follow' mechanism Zone Europe/Geneva 0:24:37 - LMT 1848 Sep 12 0:24:37 - GET 1894 Jun # Geneva MTime 0 follow Europe/Zurich For test purposes, one can simply insert this zone in the europe file. The feature is helpful in the extension of tzdata to cover complete timezone history. For this purpose, about 1000 additional zone files need to be written, and to be maintained. The process to do so has started in the astrological community, as it needs a complete pre-1970 timezone history. I will not bother you with details. I intend to help creating and maintaining a set of files like 'europe_hist', 'asia_hist' etc which contain the additional zones. The 'follow rule' will allow to keep these extra zone files very small, as usually the additional zones will all have a cross-over moment into a regular tzdata zone. I have for the moment called the modified zic source file zicx.c and prepared a patch file for zic.c to implement the 'follow rule' feature. I have tried to keep the modification very small. Please have a look at the patch, and check for the errors I have probably made. Description of the code: ------------------------ The follow rule must be the last line in a zone, and recursion is not allowed. It is parsed in inzsub() which reacts on GMTOFF = 0 and the word 'follow' in the RULE field. The zone line is stored in zones[] with a special value z_gmtoff = FOLLOW_MARK and the zone_name to follow in field z_rule (which is abused for this purpose). Before the call to outzone() the two sets of zone lines are patched together in a temporary array, so that outzone() and all functions deeper down() need not be modified.

Gaza/West Bank DST has ended
by Steffen Thorsen Sept. 24, 2012

Sept. 24, 2012

The Palestinian News & Info Agency reported on 2012-09-19 that "The three papers also said that the Palestinian government decided in its cabinet meeting on Tuesday to start winter time as of 1:00 a.m. Friday morning by turning the clock back one hour." http://english.wafa.ps/index.php?action=detail&id=20705 There are a few other sources for the same - so, West Bank is at least back on standard time, and not having found any articles stating that Gaza is having a different date, I would assume Gaza did change the clocks too. Best regards, Steffen Thorsen - timeanddate.com

Russia plans to turn it's clocks back one hour to "permanent winter time".
by Alexander Krivenyshev Sept. 23, 2012

Sept. 23, 2012

Here we are go again. Russia plans to move back from "permanent summer time" (now many areas have its time 2 hours ahead of the mean solar time) to "permanent winter time". As we mentioned in the past: Russia may move its clocks back one or two hours. (http://www.worldtimezone.com/dst_news/dst_news_russia46.html) Today, according to news, "The chairman of the State Duma's heath care committee, Sergei Kalashnikov, has submitted a bill to turn the nation's clocks back one hour to winter time - permanently ..." (http://themoscownews.com/russia/20120920/190253347.html) It is unclear if all Russian regions will turn their's clocks back one hour (in the past Kamchatka region was against moving it's clock back from UTC+12 to UTC+11). http://www.worldtimezone.com/dst_news/dst_news_russia47.html Alexander Krivenyshev, http://www.worldtimezone.com

Descriptions of the various medications
by mmm forever Sept. 19, 2012

Sept. 19, 2012

Viral diseases There are many viral diseases. Let's talk about the most common ones. Let's start with the flu virus. There are many laboratories around the world who regularly completion of stockpile vaccines and drugs to treat it. The influenza virus is most studied infectious agents. It should be noted that the epidemic virus Grip occur every year, and every few decades the epidemic of influenza is becoming a pandemic. The influenza virus has the ability to quickly change their structure. These changes affect the surface proteins - antigens, which recognizes the human immune system. Immunity of a man who developed a in contact with a variety of virus is not able to recognize the other, and when she begins her infection recognize only after full development of the disease. Antigenic variation is the ability of the virus to change its structure. It is because of her flu occur regularly. This regularity is alien to other infections, and only because of it being infected with influenza most people. Antigenic variation is of two kinds. First - antigenic drift, the second - antigenic shift. Antigenic drift - it mutations affecting two major viral proteins - hemagglutinin (H), which provides introduction of the pathogen in human cells, and neuraminidase (N), which is responsible for the output of mutated viruses from the cell. The emergence of antigenic drift is due to the fact that the enzyme, which doubles the viral RNA in the process of creating new viruses, no function of protection against errors that occur during the synthesis. These errors and lead to a mutation of the pathogen. The very same process of antigenic drift leads to a gradual change in the structure of the influenza virus, which causes it to partial or complete neuznavaniyu human immune system. It is for this reason there is a need systematically change the antigens included in the flu vaccine. Antigenic shifts - are the most significant changes in the antigenic composition of the virus. Promotes emergence antegennyh shifts that influenza can affect not only human cells, but also of animals: pigs, horses, birds, etc. In cases where the body there is more than one species of the virus, is the exchange of entire genes between viruses, thereby producing new strains of influenza, which in most cases are more aggressive than the original ones. This process and called antigenic shift. Now a wide range of antiviral drugs that you can to *buy* in our *online pharmacy <http://superpills.blogspot.com/>*. The best effect of these drugs is achieved in situations where they are beginning to use when detecting the first symptoms of influenza infection, but they are also able to facilitate the course of the disease at any stage.

Fwd: Fiji DST for 2012-2013 announced
by Arthur David Olson Sept. 12, 2012

> > Microsoft's time zone information cannot encode penultimate Sundays, > a "POSIX-style" TZ environment variable string can't encode it either! > Does zic omit the recurring rule string from the end of the version 2 tzfile in this case? zic does indeed omit the rule string in such cases. Examining such omissions is a way of identifying areas where the POSIX specification might be usefully extended (for example, recognition of a 'u' element in a time of day to specify that it's universal time--this would allow a POSIX-style Godthab rule). --ado

My (unpatched) Windows 7 machine extends the 2010 rule [Fourth Sunday October to Last Sunday March] on to infinity. They have published at least two updates since then that I've been able to find that tweak the rules, and I haven't verified firsthand but have no particular reason to doubt they similarly extend the then-latest rules [Fourth Sunday January to First Sunday March, based on update description text] indefinitely, and expect to publish further hotfixes. -- Random832
