Uncertain usage/scope of a possibly standard timezone name 'MEZ-1MSZ'
by Stephen A Hellberg Sept. 10, 2008

Sept. 10, 2008

Hello, I'm not a member of the distribution list, although I believe my enquiry is covered by its scope, and I wonder whether you might be able to circulate my enquiry (and return any replies) as my own research has failed to identify an answer. I'm trying to service a request to recognise the standard timezone name of 'MEZ-1MSZ', but I've so far not found any documentation to support or define the scope if this is an acceptable POSIX TZ value and a standard timezone name. The suggestion has been made that MSZ is a widely(?) employed alias (in some region(s) of the Gernan speaking world?) for MESZ that is standardly defined for "Mitteleuropäische Sommerzeit" (GMT+0200); MEZ being an accepted acronym for "Mitteleuropäische Zeit". And, I whilst I can find instances for the use of the standard(?) 'MEZ-1MSZ-2' I have been unsuccessful in locating any equivalence for 'MEZ-1MSZ' itself. Is MSZ equivalent and a widely accepted acronym matching MESZ, and if so where and how typical is its use? How does it differ to the 'MEZ-1MSZ-2' standard? Can you/anyone advise on the practice of employing 'MEZ-1MSZ' as a POSIX TZ value or indeed how prevalent its use is, or in which region (likely related to honouring DST somewhere in the vicinity of Berlin?) and whether this is directly equivalent to other common/standard names, such as CET-1CEST? What should its Olson equivalent be? (Whilst my inconclusive researches have been more extensive, support for the above statement appears available readily here (amongst other places): http://www.timeanddate.com/library/abbreviations/timezones/eu/cet.html http://www.timeanddate.com/library/abbreviations/timezones/eu/cest.html http://www.all-acronyms.com/special/time_zone_acronyms_and_abbreviations.asp http://de.wikipedia.org/wiki/Zeitzone ) Thank you in anticipation, Stephen --- Stephen Hellberg Java L3 Service, IBM Hursley Email: hellbes(a)uk.ibm.com Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.

Geographical extent of some tz timezones
by Eric Muller Sept. 9, 2008

Sept. 9, 2008

I am trying to clarify the geographical extent of tz timezones. For the most part, the data files provide this information, but there are a few cases which are not entirely clear. Here are a few questions; once we figure out the answers, I'll be happy to propose updates to the tz files to capture the results (in comments, of course). Thanks in advance, Eric. --- Democratic Republic of Congo. Is it correct that: The zone Africa/Kinshasa covers the (pre-2009) provinces of Bas-Congo, Kinshasa, Bandundu, and Equateur. The zone Africa/Lubumbashi covers the remainder of the Democratic Republic of Congo. ---- Kazakhstan, using the names at <http://en.wikipedia.org/wiki/Kazakstan#Provinces>. Is it correct that: Asia/Almaty = Kostanay, Karagandy, South Kaz and everything east of them Asia/Qyzylorda = Kyzylorda Asia/Aqtobe = Aktobe Asia/Aqtau = Mangystau Asia/Oral = West Kazakhstan The Atyrau province is not mentioned explictly, and given its location, it should be in one of the last three time zones, but which one? --- Indonesia. Is it correct that: Asia/Jakarta is the island of Sumatra, the island of Java. Asia/Pontianak is the provinces of West Kalimantan (Kalimantan Barat) and Central Kalimantan (Kalimantan Tengah). Asia/Makassar is the island of Sulawesi, the Lesser Sunda islands (Bali, East Nusa Tenggara, West Nusa Tenggara), the provinces of East Kalimantan, South Kalimantan. Asia/Jayapura is the provinces of Maluku, North Maluku, Papua and West Papua. --- Uzbekistan. What is the boundary between Asia/Samarkand and Asia/Tashkent? --- Marshall Islands. What is the division into Pacific/Majuro and Pacific/Kwajalein? is the later just the Kwajalein island, as this 1993 NY Times article suggests? <http://query.nytimes.com/gst/fullpage.html?res=9F0CE1D6163EF931A1575BC0A965…> --- Ukraine: what is the division of Ukraine in its four time zones, preferably in terms of the administrative divisions (e.g. <http://en.wikipedia.org/wiki/Administrative_divisions_of_Ukraine>)? --- Spain: Does the Africa/Ceuta timezone apply to all the "Plazas de soberania" or just to Ceuta proper? If the later, what is the time zone for the other places? (See <http://en.wikipedia.org/wiki/Plaza_de_soberan%C3%ADa> for a map.) --- China: the descriptions of Asia/Chongqing and Asia/Urumqui both include "west Qinghai". Shouldn't it be "east Qinghai" for Asia/Chongqing? The Asia/Urumqi zone is described as including counties of Guangdong. That seems awfully far to the east of the other areas included in that time zone. Inner Mongolia is divided between Asia/Chongqing and Asia/Shanghai. What is the division in terms of the administrative regions at <http://en.wikipedia.org/wiki/List_of_administrative_divisions_of_Inner_Mong…>? Tibet and Xinjiang are divided between Asia/Urumqi and Asia/Kashgar. What is their division in terms of the administrative regions at <http://en.wikipedia.org/wiki/List_of_administrative_divisions_of_Tibet_Auto…> and <http://en.wikipedia.org/wiki/List_of_administrative_divisions_of_Xinjiang>? --- Greenland and Antartica: what would good areas for the zones? Should they be narrow (i.e. around "inhabited" places) or wide (i.e. form a partition of the land)? --- PS. I am still nibbling at a shapefile of tz timezones for the world, which I will make available eventually. Right now, I managed to reconstruct the bulk of it from the VMAP0 data, and thereby establish a clear traceability of the map.

Olson Time Zone Database Converted to Windows Standard Time
by Tim Davis Sept. 4, 2008

Sept. 4, 2008

Hi Guys, Thought you might find this interesting. As part of an OpenID implementation I am doing, I needed the Olson TZ Database converted to Windows 'Standard' Format. I couldn't find anything online so I did it myself and have released it under an ISC Licence (http://en.wikipedia.org/wiki/ISC_license) Basically, you are free to with it what you will as long as this notice remains. I'm sure there are going to errors here and there and if you do use it - I'd appreciate a quick email with anything that is wrong or that you have updated so I can update the file and share these updates with everyone else. It's available via the link below for download as a *.xls or *.xlsx. http://www.timdavis.com.au/2008/09/03/olson-time-zone-database-to-standard-… Any feedback is welcomed and appreciated. Cheers, Tim

Pakistan extends DST through end of October?
by Paul Goyette Sept. 1, 2008

Sept. 1, 2008

I don't remember anyone posting about this recently, but one of my customers indicates that Pakistan has extended their observance of Daylight/Summer time through October 31st. Current data has DST expiring a few hours ago, at 0:00 this morning, local time. I don't have any official reference at which I can point to document the extension. Does anyone know if this is official? And if so, when might we see an update tzdata distribution?
