What is the purpose of the call to access() in localtime.c?
by Jonathan Leffler Dec. 3, 2007

Dec. 3, 2007

In localtime.c, there is the following stanza of code that opens a time zone file to file descriptor fid: { register int doaccess; /* ** Section 4.9.1 of the C standard says that ** "FILENAME_MAX expands to an integral constant expression ** that is the size needed for an array of char large enough ** to hold the longest file name string that the implementation ** guarantees can be opened." */ char fullname[FILENAME_MAX + 1]; if (name[0] == ':') ++name; doaccess = name[0] == '/'; if (!doaccess) { if ((p = TZDIR) == NULL) return -1; if ((strlen(p) + strlen(name) + 1) >= sizeof fullname) return -1; (void) strcpy(fullname, p); (void) strcat(fullname, "/"); (void) strcat(fullname, name); /* ** Set doaccess if '.' (as in "../") shows up in name. */ if (strchr(name, '.') != NULL) doaccess = TRUE; name = fullname; } if (doaccess && access(name, R_OK) != 0) return -1; if ((fid = open(name, OPEN_MODE)) == -1) return -1; } I'm puzzled about the benefit of calling access(). Won't the open() call work, or not, pretty much the same? The only reason I've thought of for why access() would fail where open() might succeed is in a programming running with setuid (or setgid) privileges, where access() would check the permissions using the real UID (and GID) but open would be controlled by the effective UID (and GID). However, it seems incorrect to prevent a setuid or setgid program from working like that -- maybe the reason the program is setuid or setgid is to permit it to access the time zone files. In terms of performance, a call to access() is only slightly less expensive than a call to open(). My concern is more about correctness than performance, though. Is there a system where using access makes a difference? -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

I have seen from http://www.twinsun.com/tz/tz-link.htm the procedure for getting the data from the 'ftp://elsie.nci.nih.gov/pub/ and how to get the timezone data files. I followed the procedures there, but I guess I am not getting a correct information in my system. I tested by writing a simple java program which will just print Date from the system. My system in in India time zone (Asia/Calcutta ) but I have TZ variable to America/Caracas ( which I think is for Venezuela ) and print the time with the fix and without the fix. I have set the system time as Jan 30 2008 ( b'se I guess Venezuela DST will start from Jan 1st ). Both tests I am getting the same time zone info. I am not sure if the procedures I am doing is correct to apply the fix. So do you have any document which describes about the implementation of this fix and how to test it. If you could consider this as a very urgent request it would be really great. thanks Salil

The most recent information I had was an article published 2007-11-22 by ABN <http://www.abn.info.ve/go_news5.php?articulo=111435&lee=7> (in Spanish). I don't read Spanish, but my understanding from that article is that the decision was still tentative, and that they didn't want to mess with the clocks before the big referendum this Sunday, as that might confuse poll times. > The official announcement was published today in the "Gaceta Oficial de la > Republica Bolivariana de Venezuela, número 38.819" (official document for > all laws or resolution publication) but is not available online yet. > > http://www.globovision.com/news.php?nid=72208 Thanks for the heads-up. I didn't know about that. That looks about as definitive as we're going to get: they plan to switch from UTC-4 to UTC-4:30 at 03:00 local time on December 9. I'll send out a proposed patch shortly.

proposed tz patch for Venezuela, St Barthelemy, St Martin (Fr.), etc.
by Paul Eggert Nov. 29, 2007

Nov. 29, 2007

Here's a proposed patch to the tz database to accommodate Venezuela's latest plans, along with the other stuff that has been accumulated recently. The following change affects near-future time stamps. * Venezuela is changing their clocks on December 9 at 03:00, instead of the January 1 at 00:00 that we thought. (Thanks to John Stainforth for the heads-up.) The following change affects the country database, but not the time data. * New links America/St_Barthelemy and America/Marigot, for the new countries St Barthelemy and St Martin (French part). (Thanks to Mark Davis for this.) The following changes affect commentary only. * Add a comment about Iran's readoption of DST. (Thanks to Roozbeh Pournader for this.) * Fix some broken links in tz-link.htm, and remove some dead links. (Thanks to Bert van Heerde for this.)

by Jonathan Leffler Nov. 25, 2007

Nov. 25, 2007

I note that the time zone information file has a version number byte and 15 bytes of currently unused (must be zero) space at the heading. Has anyone ever suggested embedding the version number of the time zone data files (eg "2007i") into that space, so that you can tell immediately where the data comes from when looking at the file? If not, may I make the suggestion? Presumably, the version byte would need to become version 3 -- or would we need both version 3 and version 4, with version 3 being like version 0 with 32-bit timestamps only plus the data version and version 4 being like version 2 with both 32-bit and 64-bit time stamps? I would suggest mandating 6 bytes, null terminated, for the version string. I don't think the version numbers for the data files ever got beyond one cycle of the alphabet in a year, so that works for almost the next seven thousand years - and after that, it is someone else's problem anyway (I plan to be retired long before that's an issue). The obvious advantage of this is that an appropriately modified zdump can show which set of rules the time zone information file was created from, which in turn would help decide whether an update is called for. The only immediate downside I can see is that the version information is not readily available in the distributed files - other than as part of the gzipped tar file name. That could be fixed if a VERSION file was released with the data, so each new release had it release number in the file. The zic program could look for that file - or take an optional argument that specifies the version. Since '-v' is for verbose, maybe '-z YYYYv'? I also note that Sun Solaris 10 appears to use the version 0 format for its time zone info files (zic --version gives 7.128). Would it be relevant to provide an output version selector option to the zic command line - so that files could be generated in version 0, 2 or 3 (or even 4) format when appropriate? Perhaps it would use "-o N" for N in 0, 2, 3 (and maybe 4)? Or do we need a more complex scheme where each of the separate data files gets a version tag whenever it is modified, so that you can tell that, for example, the northamerica rules have not changed recently, whereas the asia ones have changed? This would presumably need a new entry type in each data file - maybe Version followed by a version number, or Vrsn to be consistent with 'Rule', 'Zone', 'Link' and 'Leap' lines. -- Jonathan Leffler <jonathan.leffler(a)gmail.com> #include <disclaimer.h> Guardian of DBD::Informix - v2007.0914 - http://dbi.perl.org "Blessed are we who can laugh at ourselves, for we shall never cease to be amused."

Rules that Don't Exist
by Bill Seymour Nov. 25, 2007

Nov. 25, 2007

A tz newbie question: What happens when switching to a named rule, but no such rule exists? The Europe/Zurich example in zic.8.txt has an example of that (switches to Swiss rules in 1894, but there are no Swiss rules before 1940), but doesn't say what to do. I can make sense of that by making what seems to be the reasonable assumption that SAVE is zero and LETTER/S is null. Is that the intent? If so, then is it also true that, in America/Chicago, we should use "CT" rather than "CST" from 1883 Nov 18 12:09:24 to the last Sunday in March of 1918? Or is there something I'm missing? Thanks, --Bill Seymour

Use of tz database
by Cheryl Sallen Nov. 19, 2007

Nov. 19, 2007

Dear Messrs Olson and Eggert: This is to request assistance with my research into a suitable time zone database for use in updating commercial data products. Tele Atlas North America, Inc. ("TANA") seeks to improve the content and accuracy of time zone information within its national and global, street centerline, proprietary database. Since your website clearly describes the tz database as a public domain database, I will want to proceed as if there are no restrictions on its commercial use. If restrictions do apply, please respond to that effect. TANA data analysts have reviewed a sample of your files. I am tasked with relaying several technical observations / questions: * Is there a metadata file available? * The purpose of the code is not clear. * Can the code be 'tested'? * Will the code produce a list with state, county, and time zone (as applicable for North America, of course)? * Does your naming convention NOT reference counties' association with time zones? * Updates appear to be released 'as needed'. I believe the most recent was Oct. 1, 2007//version h? Is there an update schedule other than as needed? If the answers to these questions exist elsewhere, kindly point me to them? Your time and attention to my request will be much appreciated. Sincerely, Cheryl Cheryl J.
