Timekeeping videos
by Tim Parenti April 5, 2022

April 5, 2022

A pair of time-related videos in my recommendations today, Monday 2022-04-04: At 16:00 BST (+01), Tom Scott published a video called "How does Britain know what time it is?" about the radio time broadcasts from the UK's National Physical Laboratory, which disseminates UTC(NPL). https://www.youtube.com/watch?v=yqciKS_N0K8 Typical of his attention to detail, the wall clock Tom holds continues to tick true to time throughout the entire video, even as it cuts away to interview shots and B-roll. A couple hours later, at 18:00 BST, the British comedy panel quiz show "QI" published a clip of their episode "Rude", originally aired 2020-05-28, in which the panel discusses, among other things, how Denmark hasn't updated its laws to officially use UTC instead of Mean Solar Time. https://www.youtube.com/watch?v=jRMD9LRmRA4 -- Tim Parenti

zone file format very strict
by Alois Treindl April 1, 2022

April 1, 2022

Hi I noticed that the last line of a zone file like # Zone NAME STDOFF RULES FORMAT [UNTIL] Zone Asia/Kabul 4:36:48 - LMT 1890 4:00 - +04 1945 4:30 - +0430 does not suffer a trailing TAB character, behind the +0430 I think the zone file compiling mechanism could be a bit more tolerant of trailing white space. The issue came about because I employ a zone file generator utility, which accidentally created such trailing tabs in some cases. I fixed my generator, but wanted to mention this anyway.

indentation in localtime.c
by Roland Illig March 31, 2022

March 31, 2022

Hi, I had a look at tzcode/localtime.c today, and the indentation looks like a mess. It's a wild mixture between 2 spaces, 4 spaces, 1 tab, 2 tabs, and I couldn't see any pattern or reasonable rule set that would account for the whole file. Is this apparent mess intentional? If so, what is the history and rationale behind it? If not, who can fix this? Roland

Regarding time zone changes in Chile
by Juan Correa March 31, 2022

March 31, 2022

Hello everyone: A few days ago, I've seen some mails regarding time zone changes, specially regarding Punta Arenas. I found https://www.horaoficial.cl/historia_hora.php ; a page (with a terrible slider) with more details regarding time zones in Chile What comes for bringing this page is for 2 points, brought by Alois Treindl a few weeks ago: - From January 10, 1910, the Official Time Zone for all of Chile was set to GMT -5. I've got to check through the exact wording, but it's important to keep track that legally, all Chile has an uniform common time zone (that, obviously, started to change from 1916). - On August 22, 1927, DST was established as "hora oficial de invierno" and "hora oficial de verano"; jumping from a relative time zone from Lo Espejo observatory (-4:42:46) to UTC -5 during winter (and GMT -4 during summer). As there's a decree establishing that, I will request it to share; but using the same principle, the time zone for all of Chile was standardized using those 2 time zones (until further notice) In other matters, I've repeatedly contacted the Ministry of Energy (as Tim could see ;) ) by Twitter, through their Information Office and now by telephone, regarding America/Punta_Arenas this saturday. What they just told me is they have to check the interpretation of the decree (…), as it says "permanently", but seems everyone skipped the date before that word. I've also checked Diario Oficial (our legislation gazette) from March 1; and there is no decree yet. I will try other ways to get as soon as possible that information. However, vox populi, everyone is assuming Punta Arenas (and Magallanes) will keep UTC -3; so I think it was a sensible assumption back in the day -- Juan Correa Poblete PS Labs (http://www.pslabs.cl)

America/Dawson_Creek
by Michael Ewert March 28, 2022

March 28, 2022

Hello. TZ is a great database for all the different clocks in the world, and their changes. Thank-you for researching and maintaining such a great resource. America/Dawson_Creek has coordinates listed as +5946-12014, however I believe that the intended coordinates are +5546-12014. Thank-you for your work keeping the world ticking. Michael Ewert

Time zone in the news
by Arthur David Olson March 27, 2022

March 27, 2022

'Autocorrect in @washingtonpost <https://twitter.com/washingtonpost/>: "Gare de l'Est" becomes "Gare de l'Eastern time." Article by @Claremch <https://twitter.com/Claremch/>, "How Russian emigres scratched out a living once they lost their world of riches." Also an editing lapse of course, and no, I couldn't find this article online.' https://twitter.com/Seth4MC/status/1508059818598219777 (Not-so-fun fact: in one round of C language standardization, it took months of repeated effort to get "time zone name" changed to "time zone name or abbreviation.") @dashdashado
