LA Times: Daylight Saving Ticks Off Millions in Mexico
by Paul Eggert April 2, 2000

April 2, 2000

On page A4 of today's Los Angeles Times, staff writer Mary Beth Sheridan writes: COLIMA, Mexico--Soledad Castillo has a list of grave problems she wants Mexico's next president to solve. Low salaries. Rising crime. Poverty. But a different issue was troubling the 41-year-old cleaning woman one recent morning as she attended a campaign rally in this city in southwestern Mexico. It was something more urgent, more sinister--an evil that has aroused Mexicans nationwide in an extraordinary political backlash. Daylight saving time. Sheridan goes on to write that the issue has managed to push issues like the presidential race, poverty, and crime off the front pages. Half a dozen Mexican states have organized plebiscites on whether to implement DST, and the ruling party presidential candidate has promised to limit DST to 4 months instead of 6. Here's the URL of the complete story: http://www.latimes.com/news/nation/20000402/t000030885.html

Rational behind lcl_is_set?
by John Hawkinson March 29, 2000

March 29, 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.

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".
