Re： Inquiry to NICT about Japanese Summer time in 1948-1952.
by aya sekido Oct. 2, 2018

Oct. 2, 2018

Dear Nick, Thank you for your interest. We will respond to your inquiry. It is said that corresponding summer time was performed by instruction of the GHQ: General Headquarters (office of the Supreme Commander of the Allied Powers). We do not have detailed data about summer time then. According to the law of those days, the last day of summer time was made into 25 hours. What came after 12:59 p.m. of the last day was 00:00 a.m. of the next day. If you have any further questions, please let us know. Sincerely, Japan Standard Time Group Space-Time standards Laboratory Applied Electromagnetic Research Institute National Institute of Information and Communications Technology From: Phake Nick <c933103(a)gmail.com> Sent: Sunday, September 09, 2018 12:53 AM To: horonet(a)ml.nict.go.jp Cc: tz(a)iana.org Subject: [horonet 13333] Inquiry to NICT about Japanese Summer time in 1948-1952. To receivers of this email: Recently, I have read an article, which mentioned the history of Japanese Summer Time Implementation in the past at www.bengo4.com/internet/n_8461/ <http://www.bengo4.com/internet/n_8461/> . In the article, it was mentioned that the summer time (DST) end at 25 hours at the last day of the implementation period. Does that mean the clock would go up to the 25th hours back then and reach 24:59 before it continues toward 00:00 on the next day in standard time? If not then how did the clock switched from Summer Time back to Standard Time back then? Please use the "reply to all" function when replying to the message so that other receivers of the message can also hear answer on the matter. Sincerely, P.N.

Turkey decided to stay in +3
by Kıvanç Yazan Oct. 1, 2018

Oct. 1, 2018

Hi, Recently there was some confusion on whether Turkey was going back to +2. A decision is published today. It says all-year-long summer time (ie. UTC+3) is here to stay. No end date is specified. http://www.resmigazete.gov.tr/eskiler/2018/10/20181002-7.pdf Thanks, Kivanc Yazan

stale leap seconds file at IETF

Is the TZ community maintaining that file or is somebody at the IETF responsible for tracking NIST? -- These are my opinions. I hate spam.

When will physics make 32-bit signed leap-second counts obsolete?
by Paul Eggert Sept. 27, 2018

Sept. 27, 2018

A while ago I vaguely remember a prediction on this list of when the TZif file format will become obsolete because we have accumulated 2**31 total leap seconds if we continue to just add leap seconds as needed to keep UTC roughly in sync with TAI. To some extent this is just a playful prediction, as the format will undoubtedly become obsolete for other reasons long before then, but it's still fun to predict. Unfortunately I don't remember the details, and a quick Google search didn't find it. Does anyone else remember this? If not, I'll have to recalculate. The topic has just come up again on the tzdist-bis mailing list, which is why I'm thinking about it again. See <https://mailarchive.ietf.org/arch/msg/tzdist-bis/Q7OVmd60wydqcJahS3QRNHwtXHM>.
