switches at 1883-11-18 at the same instant

Walsh wrote in a post to a different mailing list: > Centennial: Official Enactment of U.S. Time Zones & Daylight Saving Time > A century ago today (March 19), U.S.President Woodrow Wilson signed into law the Standard Time Act of1918, which officially established time zones in the United States aswell as Daylight Saving Time.

As one would expect, the switch was done at a single instant, when UT was 1883-11-18 + 18 h. This differs from the current description in tzdb which uses different instants for different target time zones -- not a likely choice for simplifying a nationwide railway schedule. Thus I propose: - Zone America/Los_Angeles -7:52:58 - LMT 1883 Nov 18 12:07:02 + Zone America/Los_Angeles -7:52:58 - LMT 1883 Nov 18 10:07:02 - Zone America/Boise -7:44:49 - LMT 1883 Nov 18 12:15:11 + Zone America/Boise -7:44:49 - LMT 1883 Nov 18 10:15:11 - Zone America/Phoenix -7:28:18 - LMT 1883 Nov 18 11:31:42 + Zone America/Phoenix -7:28:18 - LMT 1883 Nov 18 10:31:42 - Zone America/Denver -6:59:56 - LMT 1883 Nov 18 12:00:04 + Zone America/Denver -6:59:56 - LMT 1883 Nov 18 11:00:04 - Zone America/North_Dakota/Beulah -6:47:07 - LMT 1883 Nov 18 12:12:53 + Zone America/North_Dakota/Beulah -6:47:07 - LMT 1883 Nov 18 11:12:53 - Zone America/North_Dakota/New_Salem -6:45:39 - LMT 1883 Nov 18 12:14:21 + Zone America/North_Dakota/New_Salem -6:45:39 - LMT 1883 Nov 18 11:14:21 - Zone America/North_Dakota/Center -6:45:12 - LMT 1883 Nov 18 12:14:48 + Zone America/North_Dakota/Center -6:45:12 - LMT 1883 Nov 18 11:14:48 - Zone America/New_York -4:56:02 - LMT 1883 Nov 18 12:03:58 + Zone America/New_York -4:56:02 - LMT 1883 Nov 18 13:03:58 Michael Deckers.

Keeping track of Japanese Era data
by Florian Weimer March 17, 2018

March 17, 2018

Would the tz project be interested in keeping track of the Japanese Era information? glibc currently stores it as part of its locale data, but I think this causes some issues (particularly with downstream builds). Thanks, Florian
