The file ftp://elsie.nci.nih.gov/pub/tzdata1998g.tar.gz is now available; it incorporates the Lithuanian change provided by mgedmin(a)pub.osf.it; it also moves creation of the GMT link with Etc/GMT to "etcetera" (from "backward") to ensure that the GMT file is created even where folks don't want the "backward" links (as suggested by Paul Eggert). --ado

Time zone suggestions for draft-ietf-calsch-ical-08.txt
by Paul Eggert Aug. 10, 1998

Aug. 10, 1998

Here are some suggested improvements, in the area of time zones, to the latest iCalendar draft (which I got from: ftp://ftp.isi.edu/internet-drafts/draft-ietf-calsch-ical-08.txt ). * A more consistent naming strategy for TZIDs. The current draft is inconsistent: for the same time zone it sometimes says "America-New_York", sometimes "America-New York", and sometimes other things like "Eastern". TZIDs are arbitrary, but a good naming convention can help reduce the number of errors, ease maintenance, and improve interoperability. iCalendar should recommend, but not require, the names in the public-domain Olson database (omitting the names present there only for backwards compatibility); this is the best widely-available prior art. For NYC this name would be "America/New_York". * A reference to the Olson database prior art. Many potential implementers don't know about this useful source, and have thereby propagated incorrect time zone data. * Allow UTC offsets that are not multiples of one minute. This is needed for historically recent applications (e.g. the time zone in Liberia up to 1972). * The examples should be a tad more careful about distinguishing between US Eastern time and New York time, since there was a lot of confusion about the Eastern time zone before, say, 1976. Here's a proposed line-by-line patch to the -08 draft, which embodies these suggestions. --- draft-ietf-calsch-ical-08.txt Wed Jul 15 10:41:12 1998 +++ draft-ietf-calsch-ical-08.txt-fix Thu Jul 16 17:27:13 1998 @@ -1730,7 +1730,7 @@ The following are examples of this property parameter: - DTSTART;TZID=America-New_York:19980119T020000 + DTSTART;TZID=America/New_York:19980119T020000 @@ -1740,7 +1740,7 @@ Internet Draft C&S Core Object Specification June 29, 1998 - DTEND;TZID=America-New_York:19980119T030000 + DTEND;TZID=America/New_York:19980119T030000 The TZID property parameter MUST NOT be applied to DATE-TIME or TIME properties whose time values are specified in UTC. @@ -2031,7 +2031,7 @@ section on Time Zone.

To IERS users >From: IERS Central Bureau (iers(a)obspm.fr) Subjects : New format in the permanent EOP(IERS)97 C 04 solutions for 1998 : Removal of the previous EOP(IERS) C01, C01, C03 and C04 in CB ftp Dear Colleagues, Please note the following changes in the EOP solutions of the IERS Central Bureau: 1 - New format in the permanent EOP(IERS)97 C 04 solutions for 1998 To align to the format used by USNO VLBI analysis center and those recently adopted by the IGS, the IERS Central Bureau will adopt a new format with an extra digit for polar motion and UT/LOD. This change starting from July 1998 will be first applied to the permanent EOP(IERS)97 C 04 for 1998 and the combined IERS/CB GPS solution (IERS)97 P 01. It will progressively be applied for other previous years of C04 and also to all combined solutions C01, C02 and C03. The new format for the C04 solution is the following: => FORMAT(2X,A4,I3,2X,I5,2F9.6,F10.7,2X,F10.7,2X,2F9.5) Note: The precision in the determination of Earth Orientation Parameters has dramatically increased over the latter few years thanks to the improvement in techniques and in data analysis. The IGS community has recently decided to add an extra digit to Polar Motion and UT/LOD estimates primarily for the sake of meaningful formal solution sigmas. GPS Analysis centers are progressively introducing this new format. It is clear however that the accuracy of 1 micro-arcsecond in polar motion and 0.1 micro-second for UT/LOD (corresponding to 0.3 mm on the earth surface) is not yet reached. 2 - EOP(IERS) C 01, C02, C03 and C04 which were the current solutions before the adoption of the "1997 system" (see gazettes 8 and 16) will be removed from the web/ftp site on 1 September, 1998. These series will still be available on request (iers(a)obspm.fr)

Re: FW: Order of listing month, day, and year in local date formats.

For example, the U.S. uses > month-day-year order. The POSIX locale desriptions ftp://dkuug.dk/i18n/WG15-collection contain specification for many countries and in the LC_TIME category descriptions the field named d_fmt specifies a strftime format to print dates. -- ---------------. drepper at gnu.org ,-. 1325 Chesapeake Terrace Ulrich Drepper \ ,-------------------' \ Sunnyvale, CA 94089 USA Cygnus Solutions `--' drepper at cygnus.com `------------------------
