localized date without time
by Alejandro Colomar Feb. 12, 2025

Hi Paul, Link: <https://github.com/shadow-maint/shadow/issues/1057> Currently, shadow utils' passwd(1) (and several other programs) uses UTC time when printing. That is: $ passwd -S alx alx P 2023-09-20 0 99999 7 -1 the date from above is a UTC representation of $ sudo cat /etc/shadow | grep alx | cut -f3 -d: 19620 However, shadow utils programs, such as chage(1), use local time in input. That timestamp was set by chage(1), interpreting a local date: $ sudo chage -d 2023-09-21 alx $ sudo cat /etc/shadow | grep alx | cut -f3 -d: 19620 $ date Wed Jul 31 07:54:17 CEST 2024 This is rather confusing, and we think that passwd(1) should also print the date in local time, when printing human-readable dates. However, I think it might be better to show the timezone information together with the date, to be clear that what we're printing is local time. Do you think that's reasonable? Or maybe it's understood that when printing a date some timezone information is implicitly local? I didn't find any way to print timezone information in ISO 8601, if you don't print the time together with the date. That is, ISO 8601 says: C.1.3.1 Date A date string represents one of the following: • year, month, and day (e.g. 2001-02-03) • year and month (e.g. 2008-12 ) • year (e.g. 2008) and C.1.3.2 Date and Time A date/time string is composed according to one of three representations as illustrated in the following three examples: • 2001-02-03T09:30:01 • 2004-01-01T10:10:10Z • 2004-01-01T10:10:10+05:00 but I don't see any way to print something like 2023-09-21+02:00 in standardese. Is this a defect in ISO 8691? I see that in C.1.3.2, it says "Zone-offset may be omitted or included", so I guess we can just omit it. What do you think we should do? Thanks! And have a lovely day!

Paraguay may adopt permanent DST soon
by Heitor David Pinto Jan. 13, 2025

Jan. 13, 2025

Today the Congress of Paraguay passed a bill to observe UTC-3 permanently, equivalent to permanent DST. The bill still needs to be approved by the president. https://www.abc.com.py/politica/2024/09/24/congreso-sanciona-horario-de-ver… The text of the bill says that it would enter into force on the first Sunday in October 2024, the same date currently scheduled to start DST. But in practice, it would only make a difference from the fourth Sunday of March 2025, the date currently scheduled to end DST. https://silpy.congreso.gov.py/web/expediente/132531

New timezone Antarctica/Concordia (UTC+8)
by Erik Geletti Nov. 25, 2024

Nov. 25, 2024

Goodmorning. I'm writing here to propose a new time zone for an all-year open Antarctic base. The base is a French–Italian research facility that was built 3,233 m (10,607 ft) above sea level at a location called Dome C on the Antarctic Plateau, Antarctica. https://en.wikipedia.org/wiki/Concordia_Station The timezone is UTC+8 without DST.

Ukraine to abolish DST?
by Steffen Thorsen Oct. 26, 2024

Oct. 26, 2024

Ukraine seems to be getting rid of DST, according to https://universemagazine.com/en/the-verkhovna-rada-canceled-daylight-saving… "During a meeting of the Verkhovna Rada of Ukraine on June 16, daylight saving time was canceled. According to MP Yaroslav Zheleznyak, 261 MPs voted in favor of the bill. Now it must be signed by the President of Ukraine, and then it will come into force." which is again referencing (in Ukrainan) https://lb.ua/society/2024/07/16/624453_verhovna_rada_skasuvala_perehid.html It seems they will plan to set back time this autumn to winter(standard) time, and then stay on that. Best regards, Steffen Thorsen - timeanddate.com

Brazil may reinstate daylight saving time soonish
by Paul Eggert Oct. 16, 2024

Oct. 16, 2024

A Reuters report[1] says that energy authorities in Brazil have approved a plan to bring back daylight saving time, to save electrical energy during a major drought that has hurt hydroelectric power generation[2]. As far as I know authorities have not decided or published details of the plan, such as which states would be involved and dates and times of transitions. However, one English-language report says that DST would not start until after the election period ends on October 27[3]. This is not a done deal, as any change would need approval by President Luiz Inácio Lula da Silva. That being said, Brazil's DST was abolished by Lula's predecessor and political opponent Jair Bolsonaro, and Lula did an informal Twitter poll shortly after his election in which 66% of respondents voted for DST[4], so presumably Lula would favor restoring DST.
