by Paul Eggert May 25, 2015

May 25, 2015

It's March Madness time for daylight-saving rule changes. Here's a proposed change to the tz database to keep up with the latest political development, which affects time stamps starting March 29: * Latvia and Lithuania will not observe DST, starting this year.

Rational behind lcl_is_set?
by John Hawkinson March 28, 2000

March 28, 2000

[ If you could cc me on replies until my subscription request is processed, I'd appreciate it. ] I recently made the oberservation that tzset() seems to keep state on whether it has read the system localtime file and if so, subsequent invokations of tzset() do not re-read the file. This seems to prevent applications which call tzset() from obtaining new time zone information should the system change. For instance, my laptop recently travelled through: US/Eastern -> US/Central -> US/Pacific -> Pacific/Gambier -> Pacific/Honolulu -> Pacific/Midway -> Pacific/Fiji -> Pacific/Auckland -> Pacific/Kosrae -> Australia/Sydney -> Australia/Adelaide during which time my /etc/localtime file changed as appropriate. It would have been nice if, had my MUA called tzset() across each time zone, times would have been correct. But tzset() seems to cache old data. In my case, $TZ is unset so tzsetwall() is called, and it's first act is: if (lcl_is_set < 0) return; lcl_is_set = -1; So there seems to be no hope of causing tzset() to re-read this data. Ironically enough, it seems that if the value of TZ changes, tzset() will change state. This seems odd as it seems far more likely that the system's /etc/localtime file will change, than a process will actually change its own TZ environment variable in mid-flight. I presume that this caching was added as an optimization since strftime() calls tzset() during each invokations. Is there no way around it, short of changing the API and adding some function to reload timezone data, or giving up the caching and having tzset() reread localtime each time? The presence of STD_INSPIRED implies that new functions could be added, but I presume there's a relatively high hurdle to doing so. Incidently, tzset() seems a bit underdocumented. Specifically newtzset(3) fails to indicate whether programs should call tzset() by hand, or whether they should never bother, etc., etc. If I knew the answer I would offer a patch. Thanks. --jhawk p.s.: You're free to tell me that I'm foolish for wanting my time to change accurately on transoceanic flighs, but it is terribly nice to have one's mail timestamped appropriate, at the very least.

Lithuanian time zone update
by Marius Gedminas March 26, 2000

March 26, 2000

Lithuania gave up shifting to summer time as planned. Here is a patch for europe file from tzdata2000d.tar.gz. Note that I'm not sure about the exact time of this change, I just copied 1:00u from the line above. Marius Gedminas -- "Linux: the operating system with a CLUE... Command Line User Environment".
