Time Zones - Canary Islands - Offshore Spain - Error
by moxhull May 15, 2015

May 15, 2015

Dear Paul Eggert, I use software which sources your data in github for time zones. The Canary Islands, located off the coast of Morocco, belong to Spain but have a different time zone. It's causing me problems because it seems your files do not take account of this. Would you kindly amend your files accordingly, please, so that my software programmer can use an updated file, so in turn I can use his software? Please see below for references. Many thanks indeed, so grateful. Yours sincerely, Sylvie ---------- Forwarded message ---------- From: Anatoly Zaytsev <astrozet(a)gmail.com> Date: Thu, May 14, 2015 at 5:41 PM Subject: Re: Zet 8 Geo, time zones To: moxhull <moxhull(a)gmail.com> Hello Sylvie, 1) This is not so important. 2) I use more (seems) relevant source: https://github.com/eggert/tz Paul Eggert tz-bounces(a)iana.org also https://github.com/eggert/tz/blob/master/europe line 2922 Please talk with him. ----------------- Anatoly Zaytsev www.astrozet.com ----- Original Message ----- From: "moxhull" <moxhull(a)gmail.com> To: <astrozet(a)gmail.com> Sent: Thursday, May 14, 2015 7:02 PM Subject: Zet 8 Geo, time zones Dear Anatoly, I hope you are well. I write for two items: - I have retired from my job in Geneva (Switzerland), sold my house in France, and I have moved to the Canary Islands, a part of Spain that is off the coast of Morocco. So my addresses, email and telephone number need to be changed in your records - see below. - The Canary Islands do not use the same time as mainland Spain, so I'm having trouble with the time changes. I tried to make a few modifications in my Zet but I do not know enough and did not succeed. Please would make the corrections in the time zone files and make them available? For reference see: http://en.wikipedia.org/wiki/Time_in_Spain#The_Canary_Islands_exception Thank you very much for correcting this. Kind regards, Sylvie Weber Calle Aceviño 49 Ed.

Question about IANA time zone names
by Avila, Edgar May 15, 2015

May 15, 2015

Hi, I'm a software engineer working on the data modeling group. We are trying to figure out how the IANA time zone names can be described on our message model. At the modem it seems that the time zone names such as America/Costa_Rica or Japan are just a string without restrictions. We wonder whether there is a restriction such as maximum length of characters, pattern of characters to allow, etc. One more question, is it really America/Costa_Rica or Japan a name or an ID? The following is the description we have today in one of our schemas: <xs:simpleType name="IANATimeZoneId_Type"> <xs:annotation> <xs:documentation> Timezone Id represented by IANA. </xs:documentation> </xs:annotation> <xs:restriction base="xs:string"/> </xs:simpleType> Thanks in advance ________________________________ [https://www.aciworldwide.com/photolibrary/ACI_logotag_footer.gif]<http://www.aciworldwide.com> This email message and any attachments may contain confidential, proprietary or non-public information.

Thanks for reporting that. I installed the attached patch into the experimental tz version on github <https://github.com/eggert/tz>, with the intent that this fix propagate into the next tz release and thus into glibc etc.

Problem with tzselect and Dominica
by Owen Leibman May 12, 2015

May 12, 2015

Using a freshly downloaded version of tzelect, and choosing 2 (Americas) followed by 18 (Dominica), the following results: ./tzselect: line 469: /usr/share/zoneinfo/ America/Port_of_Spain: No such file or directory ./tzselect: time zone files are not set up correctly I believe that is because Dominica's abbreviation (DM) is actually found in some comments near the head of the file. To avoid this problem, I believe he awk statement at line 463: $1 ~ cc && $4 == region { print $3 } needs to be changed thus to exclude comment lines: $0 !~ /^#/ && $1 ~ cc && $4 == region { print $3 }

[PROPOSED PATCH 1/3] Remove hair from southamerica comment
by Paul Eggert May 4, 2015

May 4, 2015

While using the tz source to test some other program I found an unwanted hair space (U+200A) in the commentary. Fix this, and adjust Makefile to catch this sort of thing in the future. * Makefile (SAFE_CHARSET): Exclude ] and -, as they're now the invoker's responsibility. Invoker changed. (NONSYM_CHAR): Remove, replacing with ... (OK_CHAR): ... this new macro. All uses changed. (NONSYM_LINE, VALID_LINE): Remove, replacing with ... (OK_LINE): ... this new macro. All uses changed. (check_character_set): Simplify test, and report all non-ASCII non-letters. Remove the exception for Makefile, as it no longer needs to contain non-OK characters. * southamerica: Replace an inadvertent hair space with a space. --- Makefile | 30 ++++++++++++++---------------- southamerica | 2 +- 2 files changed, 15 insertions(+), 17 deletions(-) diff --git a/Makefile b/Makefile index b398727..c3b23c8 100644 --- a/Makefile +++ b/Makefile @@ -292,23 +292,24 @@ TAB_CHAR= ' ' SAFE_CHARSET1= $(TAB_CHAR)' !\"'$$sharp'$$%&'\''()*+,./0123456789:;<=>?@' SAFE_CHARSET2= 'ABCDEFGHIJKLMNOPQRSTUVWXYZ[\\^_`' SAFE_CHARSET3= 'abcdefghijklmnopqrstuvwxyz{|}~' -SAFE_CHARSET= ]$(SAFE_CHARSET1)$(SAFE_CHARSET2)$(SAFE_CHARSET3)- -SAFE_CHAR= '['$(SAFE_CHARSET)']' -# NONSYM_CHAR is a regular expression that matches any character -# except for a small number of symbols, where we prefer to stick with +SAFE_CHARSET= $(SAFE_CHARSET1)$(SAFE_CHARSET2)$(SAFE_CHARSET3) +SAFE_CHAR= '[]'$(SAFE_CHARSET)'-]' + +# OK_CHAR matches any character allowed in the distributed files. +# This is the same as SAFE_CHAR, except that multibyte letters are +# also allowed so that commentary can contain people's names and quote +# non-English sources.
