RE: DOT issues final ruling on Indiana time zones

Since this is in the spring, shouldn't that last change be from 2AM CST to 3AM CDT? ++PLS -----Original Message----- From: tz-request(a)elsie.nci.nih.gov [mailto:tz-request@elsie.nci.nih.gov] On Behalf Of Deborah Goldsmith Sent: Wednesday, January 18, 2006 5:38 PM To: tz(a)lecserver.nci.nih.gov Subject: DOT issues final ruling on Indiana time zones <snip> assuming I'm interpreting everything correctly. The DOT doesn't specify whether Starke county switch to Central Time at the appropriate time for its old or new time zone, but I'm assuming the old here. That leads to it falling back from 2:00AM EST to 1:00AM CST, and then again from 2:00AM CST to 1:00AM CST. If that makes people nervous, then the transition would need to be at 3:00 AM.

In the UK, the first of these would be "section 1 of chapter 7 of the laws of 1965"; chapter 7 is, in turn, the 7th Public Act passed in that year. Since the cited work says "This Act is consolidated to <date>", I presume it's a publication that applies all the various amending Acts up to that date. Hmm; 2005 c.7 is "An Act Respecting Rural Communities" <http://www.gnb.ca/0062/acts/BBA-2005/Chap-7.pdf>. Section 83 is titled "Time Definition Act" and, found on page 123, reads: 83 Subsection 1(1) of the French version of the Time Definition Act, chapter T-6 of the Revised Statutes, 1973, is amended by striking out "municipal". It looks to me as if your original document cites all the bits of legislation you need to look up to determine the changes.

The Washington Post's Monday, December 26, 2005 edition includes, on page A17, the story "Added Ticktock of the Clock Restarts Time Debate." The story is precipitated by the upcoming leap second. (My guess is that author Guy Gugliotta wrote it well in advance rather than on Christmas Day.) The story is available from http://washingtonpost.com; free registration is required. --ado

New Brunswick switches at 00:01, not 02:00; new Zone needed
by Paul Eggert Dec. 21, 2005

Dec. 21, 2005

I found a copy of New Brunswick's Time Definition Act consolidated to 2005-07-15 <http://www.gnb.ca/0062/PDF-acts/t-06.pdf> and it confirms that New Brunswick switches to and from DST at 00:01 rather than 02:00. So we need a new Zone. I am thinking of using the name America/Moncton. Moncton has approximately the same population as Saint John, but the latter name is uncomfortably close to the already-existing Zone America/St_Johns. Page 2 of the above reference says "1965, c.7, s.1; 1973, c.74, s.75; 1993, c.9, s.1; 2005, c.7, s.83." I assume this refers to dates when the law changed, which would be useful for tracking down the history of America/Moncton. I did track down an older version of the consolidated document <http://www.canlii.org/nb/laws/sta/t-6/20030127/whole.html> which makes it clear that they haven't changed the rules since 1993 at least, but I can't go earlier than that in the canlii.org database. For dates before 1993 I'll probably defer to Shanks, unless someone else can track it down.

Manitoba, Ontario, P.E.I., Quebec adopt 2007 US DST change
by Paul Eggert Dec. 21, 2005

Dec. 21, 2005

I looked around for news reports of the effect on the US's 2007 daylight-saving plans on Canada, and found reports that Manitoba, Ontario, P.E.I., and Quebec are committed to switching, and other provinces are thinking of switching. My assumption is that all of Canada (save perhaps Newfoundland) will switch, but that it's too early to regard this as official. One problem is how to reflect this in the tz database. I'm inclined to propose something along the following lines, at least for now, to keep the tables simple; we should be able to fix things before 2007 if some of the provinces decline to follow the US lead.

Small changes to make tz data files more readable when used as html
by Olson, Arthur David (NIH/NCI) [E] Dec. 13, 2005

The changes below just add "<pre>" directives to each of the primary data files (which, coincidentally, are the ones that contain "<a href=.*>" stuff); this makes them more readable when they're given ".htm" extensions and made available to browsers. Yes, more would need to be done to make this legitimate, but it works for my purposes and, I hope, works for yours as well. --ado ------- africa ------- *** /tmp/geta10846 Tue Dec 13 10:36:00 2005 --- /tmp/getb10846 Tue Dec 13 10:36:00 2005 *************** *** 1,4 **** ! # @(#)africa 7.39 # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to --- 1,5 ---- ! # @(#)africa 7.40 ! # <pre> # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to ------- antarctica ------- *** /tmp/geta10865 Tue Dec 13 10:36:00 2005 --- /tmp/getb10865 Tue Dec 13 10:36:00 2005 *************** *** 1,4 **** ! # @(#)antarctica 7.29 # From Paul Eggert (1999-11-15): # To keep things manageable, we list only locations occupied year-round; see --- 1,5 ---- ! # @(#)antarctica 7.30 ! # <pre> # From Paul Eggert (1999-11-15): # To keep things manageable, we list only locations occupied year-round; see ------- asia ------- *** /tmp/geta10884 Tue Dec 13 10:36:00 2005 --- /tmp/getb10884 Tue Dec 13 10:36:00 2005 *************** *** 1,4 **** ! # @(#)asia 7.89 # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to --- 1,5 ---- ! # @(#)asia 7.90 ! # <pre> # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to ------- australasia ------- *** /tmp/geta10903 Tue Dec 13 10:36:01 2005 --- /tmp/getb10903 Tue Dec 13 10:36:01 2005 *************** *** 1,4 **** ! # @(#)australasia 7.77 # This file also includes Pacific islands. # Notes are at the end of this file --- 1,6 ---- ! # @(#)australasia 7.78 ! # <pre> ! # This file also includes Pacific islands. # Notes are at the end of this file ------- europe ------- *** /tmp/geta10922 Tue Dec 13 10:36:01 2005 --- /tmp/getb10922 Tue Dec 13 10:36:01 2005 *************** *** 1,4 **** ! # @(#)europe 7.95 # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to --- 1,5 ---- ! # @(#)europe 7.96 ! # <pre> # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to ------- northamerica ------- *** /tmp/geta10941 Tue Dec 13 10:36:01 2005 --- /tmp/getb10941 Tue Dec 13 10:36:01 2005 *************** *** 1,4 **** ! # @(#)northamerica 7.82 # also includes Central America and the Caribbean # This data is by no means authoritative; if you think you know better, --- 1,6 ---- ! # @(#)northamerica 7.83 ! # <pre> ! # also includes Central America and the Caribbean # This data is by no means authoritative; if you think you know better, ------- southamerica ------- *** /tmp/geta10960 Tue Dec 13 10:36:02 2005 --- /tmp/getb10960 Tue Dec 13 10:36:02 2005 *************** *** 1,4 **** ! # @(#)southamerica 7.65 # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to --- 1,5 ---- ! # @(#)southamerica 7.66 ! # <pre> # This data is by no means authoritative; if you think you know better, # go ahead and edit the file (and please send any changes to

Thanks for the suggestions on the the bad URLs. I tracked down a replacement for the New-South-Wales-specific page. I'd like to keep the no-longer-working URL for Heard Island since there's no other source for that information.

If memory serves, the latter form (*(unsigned char *)cp) is not portable to all C89 hosts, whereas the former form ((unsigned char) *cp) is. The idea is that some C89 hosts might have padding bits in their unsigned char representation, and it's incorrect to access a char as if it were unsigned char. I believe this issue got cleared up in C99, so the code is portable to C99 compilers. But the zic stuff attempts to be portable to C89 (as well as earlier) compilers. > it is certainly true that it's possible to test for digits by using > >= '0' && <= '9' tests - but if that's the best way to write it, > then that's what isdigit() ought to be doing. Alas, that's not true in practice. isdigit is typically slower, and it can be quite a bit slower. For example, on my host (Debian GNU/Linux stable, GCC 4.0.2, gcc -O4), with the following code: int F (char *p) { return isdigit ((unsigned char) *p) != 0; } int G (char *p) { return '0' <= *p && *p <= '9'; } F compiles into 12 instructions that contain a subtroutine call (for a total of 31 instructions executed), whereas G compiles into 10 instructions of straight-line code. I think part of the problem is that isdigit might be sensitive to the locale. So there's a correctness issue here as well; isdigit might actually return the wrong value, since it might think that some other byte code is a digit. (This is just a theoretical issue, as far as I know, though.) > Paul's version may be textually shorter, but with that cp++ side > effect buried in the middle of the && sequence, it is not nearly as > easy to read. True, but in my defense that buried cp++ was in the original code. How about this instead? It might be a bit clearer. char c = *cp; if ('0' <= c && c <= '9') { cp++; if (c == '1' && '0' <= *cp && *cp <= '4') cp++; }

Than again, and I haven't looked at the code again just now to see if it is practical or not, but an alternative might just be to declare cp as being unsigned char * right from the start (even if that means that it needs to stop being an input parameter, and instead be copied from one which would need to remain char * to avoid changing the API). kre ps: I don't think Paul's suggested variation is really the right thing to do - it is certainly true that it's possible to test for digits by using >= '0' && <= '9' tests - but if that's the best way to write it, then that's what isdigit() ought to be doing. If you want to make it shorter, it is safe to stop the isascii() test if the arg is known to be unsigned char which after this change, it will be (or EOF, but that's irrelevant here). Paul's version may be textually shorter, but with that cp++ side effect buried in the middle of the && sequence, it is not nearly as easy to read.
