Re: [tz] A simple JavaScript library for timezone handling

FWIW: The ECMAScript folks are working on globalization stuff for JavaScript, including looking at timezones... Of course creating new standards and getting them implemented takes a while, but I thought I'd mention it... -Shawn ---------------------------------------------------------------------- From: "L. David Baron" <dbaron(a)dbaron.org> Subject: [tz] A simple JavaScript library for timezone handling To: tz(a)iana.org A while ago I wrote a simple JavaScript library for timezone handling in JavaScript. It provides a simple API described here: https://github.com/dbaron/tz.js/blob/3489978e9422c49f1bb4aafdfeee429a3e6651… and has build scripts to convert the necessary data from the tz database into JSON format to include in the script. The end result including the code and the data, gzip-compressed, is about 74 KB. I keep hoping I'd get a chance to make some additional improvements before announcing it, but that served only to delay announcing it and not to lead to additional improvements. Since it might be useful to others in its current form, I thought I'd share it on this list. It is: https://github.com/dbaron/tz.js -David

Rule names
by Osko, Galatea Feb. 1, 2013

Feb. 1, 2013

Can anyone please advise on where I can find the Rule name history for each country/region? The data I'm interested in is as follows: - AQ, Oz: I don't know to which area/country this is referring to as it is not listed on tiscali - C-Eur, E-EurAsia - are these valid/active rule names in use? or used parallel? not sure if any of them is a historic name for Europe that's why I'm looking for archived rule names. I believe some of these were used up to some point in the past and then switched to a new name... And I also have some other countries like Pakistan, Palestine where I would like to check the DST history. ________________________________ NOTICE: Morgan Stanley is not acting as a municipal advisor and the opinions or views contained herein are not intended to be, and do not constitute, advice within the meaning of Section 975 of the Dodd-Frank Wall Street Reform and Consumer Protection Act.

zdump no longer reports gmtoff
by Marvel, Jim (CPCOE) Jan. 31, 2013

Jan. 31, 2013

Using ubuntu 12.04 LTS Using tz 2012 j code/data Tested each timezone mentioned in zone.tab, by zdump-ing each one. Observed that each timezone had two lines that reported NULL, then a bunch of nice-looking pairs-of-lines, then two lines that reported "NULL" I understand that this could be caused if you are using a 64 bit ubuntu on a 32-bit machine.... ...I may have !!! migrated to a 32-bit ubuntu on a 32-bit machine... The lines at the earliest/latest transition for each timezone are no longer "NULL"-containing (they mention 1901 and 2038, which I understand) What is breaking my heart is "Why did the lines drop off the gmtoff value, now ending with the isdst value?" Saw somewhere that tm_gmtoff is a GNU extension that may not be visible... Please "illuminate" Thanks, Jim

A Simple Question

I recently added time zone support to our product, and life would have been easier if the time zone files had their file name in them so that they 'knew' what they were. How come they don't?

Archived Rule names
by Osko, Galatea Jan. 28, 2013

Jan. 28, 2013

Hi team, Is there a list of outdated rule names that are not in use anymore? I found rule name "oz" which is supposed to be a code for Australia however the tiscali only mentions AN, AS and some other similar codes. I assume this is a historical code but I do not find this info on any of the websites. I have problems with some other as well: C-Eur AQ E-EurAsia Please advise.

Re: [tz] Bangladesh's TZ Abbreviation
by Shawn Steele Jan. 19, 2013

Jan. 19, 2013

I noticed other non-bd sites with BdST. None of the sites (for either code) seem persuasively authoritative. References to BST are 1-off references, whereas the news site uses BdST consistently, but it's just one site. I notice that Wikipedia has been using BdST for some time. (Not that I'm saying it's a good source, and it didn't cite its references). I suggest that the lack of good references is maybe because Bengali doesn't use the Latin script? I can understand why someone may want to distinguish their abbreviation from BST though. What has been the past policy for determining these abbreviations? Particularly for non-Latin scripts, &/or where it may be difficult for us to find, read, &/or transliterate any native-language sources? -Shawn

Bangladesh's TZ Abbreviation
by Hank W Jan. 18, 2013

Jan. 18, 2013

The online Bangladesh newspaper bdnews24.com repeatedly abbreviates Bangladesh Standard Time as BdST, as opposed to the BDT abbreviation in the current Asia file of the tzdata. For example, the article at http://bdnews24.com/bangladesh/2009/12/31/2010-new-decade-cheered-in, (dated 2010-01-01) states in part, "Clocks went back at 11:59pm on Thursday night--rather than midnight--to restore Bangladesh Standard Time (BdST), GMT+6." I found many similar examples in a search for BdST within the site. Searches for BdDT and BdT yielded nothing. A search for BDT yields many references to their currency, not their time. I searched also for BST and found it referring to Bangladesh Standard Time in articles from about seven or eight years ago, while in articles from the current decade it seems to be referring only to British Summer Time.
