Release 2019c - 2019-09-11 08:59:48 -0700


  • Fiji observes DST from 2019-11-10 to 2020-01-12.
  • Norfolk Island starts observing Australian-style DST.

Changes to future timestamps

  • Fiji's next DST transitions will be 2019-11-10 and 2020-01-12

instead of 2019-11-03 and 2020-01-19. (Thanks to Raymond Kumar.) Adjust future guesses accordingly.

  • Norfolk Island will observe Australian-style DST starting in

spring 2019. The first transition is on 2019-10-06. (Thanks to Kyle Czech and Michael Deckers.)

Changes to past timestamps

  • Many corrections to time in Turkey from 1940 through 1985.

(Thanks to Oya Vulaş via Alois Treindl, and to Kıvanç Yazan.)

  • The Norfolk Island 1975-03-02 transition was at 02:00 standard

time, not 02:00 DST. (Thanks to Michael Deckers.)

  • South Korea observed DST from 1948 through 1951. Although this

info was supposed to appear in release 2014j, a typo inadvertently suppressed the change. (Thanks to Alois Treindl.)

  • Detroit observed DST in 1967 and 1968 following the US DST rules,

except that its 1967 DST began on June 14 at 00:01. (Thanks to Alois Treindl for pointing out that the old data entries were probably wrong.)

  • Fix several errors in pre-1970 transitions in Perry County, IN.

(Thanks to Alois Triendl for pointing out the 1967/9 errors.)

  • Edmonton did not observe DST in 1967 or 1969. In 1946 Vancouver

ended DST on 09-29 not 10-13, and Vienna ended DST on 10-07 not 10-06. In 1945 Königsberg (now Kaliningrad) switched from +01/+02 to +02/+03 on 04-10 not 01-01, and its +02/+03 is abbreviated EET/EEST, not CET/CEST. (Thanks to Alois Triendl.) In 1946 Königsberg switched to +03 on 04-07 not 01-01.

  • In 1946 Louisville switched from CST to CDT on 04-28 at 00:01, not

01-01 at 00:00. (Thanks to Alois Treindl and Michael Deckers.) Also, it switched from CST to CDT on 1950-04-30, not 1947-04-27.

  • The 1892-05-01 transition in Brussels was at 00:17:30, not at noon.

(Thanks to Michael Deckers.)

Changes to past time zone abbreviations and DST flags

  • Hong Kong Winter Time, observed from 1941-10-01 to 1941-12-25,

is now flagged as DST and is abbreviated HKWT not HKT.

Changes to code

  • leapseconds.awk now relies only on its input data, rather than

also relying on its comments. (Inspired by code from Dennis Ferguson and Chris Woodbury.)

  • The code now defends against CRLFs in leap-seconds.list.

(Thanks to Brian Inglis and Chris Woodbury.)

Changes to documentation and commentary

  • theory.html discusses leap seconds. (Thanks to Steve Summit.)
  • Nashville's newspapers dueled about the time of day in the 1950s.

(Thanks to John Seigenthaler.)

  • Liechtenstein observed Swiss DST in 1941/2.

(Thanks to Alois Treindl.)
