[PROPOSED] Fix 'make clean' problem with clean_*.dir
by Paul Eggert March 11, 2019

March 11, 2019

* Makefile (clean_misc, clean): Use rm -fr on patterns that can match directories, so that 'make clean' works even if there is a directory check_zishrink.dir. Stick with rm -f on patterns that should match only files, for safety. --- Makefile | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/Makefile b/Makefile index 4bc72a9..25f1d35 100644 --- a/Makefile +++ b/Makefile @@ -847,11 +847,13 @@ check_zishrink_posix check_zishrink_right: \ touch $@ clean_misc: + rm -fr check_*.dir rm -f *.o *.out $(TIME_T_ALTERNATIVES) \ check_* core typecheck_* \ date tzselect version.h zdump zic yearistype libtz.a clean: clean_misc - rm -fr *.dir *.zi tzdb-*/ $(TZS_NEW) + rm -fr *.dir tzdb-*/ + rm -f *.zi $(TZS_NEW) maintainer-clean: clean @echo 'This command is intended for maintainers to use; it' -- 2.20.1

Why is `Etc/UCT` not an alias of `Etc/UTC`?
by Isiah Meadows March 10, 2019

March 10, 2019

They seem to refer to the same thing, so it doesn't make much sense to me why they're considered different. I also looked in the relevant file in the source, `/etcetera`, and there doesn't seem to be any rationale for it. Was this an oversight? ----- Isiah Meadows contact(a)isiahmeadows.com www.isiahmeadows.com

Proposed Change to Maine's Time Zone *No Current Action Needed* Update

Text of No. 144, Rep. Kessler's Proposal http://legislature.maine.gov/bills/getPDF.asp?paper=HP0126&item=1&snum=129 Seems light on substance. I remain firm that this likely goes nowhere.

Proposed Change to Maine's Time Zone *No Current Action Needed*
by C Yohman March 8, 2019

March 8, 2019

Long-time lurker, first time poster. I'm putting this on the periphery, in case it comes to pass (Probability: infinitesimal). Variations come about every decade. Not that it matters in this context, but the change would make sense for the eastern half of the state with commerce ties to New Brunswick and The Maritimes. Not so much for the western half of the state where the commerce ties are strong to New Hampshire & Massachusetts. That's just a slice of the perspective. Ironically, the two measures were introduced by two southern Maine representatives. Summary: "The two bills are proposed by Democratic lawmakers and take different approaches to eliminating the time change. Rep. Chris Kessler of South Portland’s bill would move Maine into the Atlantic time zone, which would mean the state would no longer set clocks back in fall. Rep. Donna Bailey, of Saco, has proposed keeping Maine in daylight saving time all year if the federal government also does so. Florida passed a similar bill."

Google Chrome -> New Incognito Window is your option for multiple free views) Further Sources: https://wgme.com/news/local/bill-would-move-maine-into-atlantic-time-zone Rep. Kessler & Rep. Bailey have been contacted for the Reference LD # or further information. Sample email sent: Representative Kessler, Citizen of Waterboro, Maine here (work in Portland, commute through a sliver of South Portland), but I read your name is attached to one of the bills. "Rep. Chris Kessler of South Portland’s bill would move Maine into the Atlantic time zone, which would mean the state would no longer set clocks back in fall." https://www.pressherald.com/2019/03/07/bills-would-say-good-night-to-daylig… I have no opinion on the matter, but if there was a change there would likely need to be a change to tzdata, the database that keeps track of timezones across the world. https://www.iana.org/time-zones Ultimately, at a basic level, it allows you to set the correct timezone on your electronic devices. What is the LD number for the measure, or where can I read the proposed text to understand the proposed change better? Regards, Chance Yohman Follow-Up: Hearing scheduled for March 11th. Will update when I know.

Arbitrary default system time?
by Arthur David Olson March 7, 2019

March 7, 2019

A question about current operating systems. They have differing ways of establishing a system-wide default local time zone at installation time. Are the current ways flexible enough to allow establishing a zone that's not in the database (for example, Freedonia Standard Time--FST--for a newly created country)? (If not, adding a zic option to help with the matter might be of use.) @dashdashado
