Coordinates format
by Jonas Melian Feb. 4, 2009

Feb. 4, 2009

Hi, I've seen that is used the format "+-DDMM+-DDDMM" or "+-DDMMSS+-DDDMMSS" to represent latitude and longitude according to ISO-6709 [1] standard. 1) But, the standard is used whith decimals: ±DDMM.MMM ±DDDMM.MMM (degrees and minutes) ±DDMMSS.SS ±DDDMMSS.SS (degrees, minutes and seconds) 2) Could your database to use one only way to represent the format? Or degrees and minutes; or degrees, minutes and seconds. So, the coordinates could be stored as float in the data bases, since that we know its total length. Greetings!

"Extended" POSIX time zone string?
by Olson, Arthur David (NIH/NCI) [E] Feb. 3, 2009

Feb. 3, 2009

Future transitions in a zone such as America/Godthab can't be represented by a POSIX time zone string. Transitions could be represented by a string such as... WGT-3WGST,M3.5.0/1u,M10.5.0/1u ...where the "1u" is an indication that transitions occur at 1:00 a.m. Universal time. Is this format extension (or something better) worth suggestion to the POSIX powers? --ado

Proposed time zone package changes
by Arthur David Olson Feb. 2, 2009

Feb. 2, 2009

Below find proposed relatively minor proposed changes to the time zone package: * leapseconds: updated to reflect no mid-2009 leap second * tz-art.htm: information on two CDs added * zic.c: fix fencepost error The change to zic.c will result in changed binary outputs in a handful of cases. If no one spots problems, these changes should appear at ftp://elsie on 2009-02-08. --ado diff -c -r old/leapseconds new/leapseconds *** old/leapseconds Wed Jan 14 17:35:16 2009 --- new/leapseconds Tue Jan 27 15:46:54 2009 *************** *** 1,4 **** ! # @(#)leapseconds 8.6 # Allowance for leapseconds added to each timezone file. --- 1,4 ---- ! # @(#)leapseconds 8.7 # Allowance for leapseconds added to each timezone file. *************** *** 53,92 **** # SERVICE DE LA ROTATION TERRESTRE # OBSERVATOIRE DE PARIS # 61, Av. de l'Observatoire 75014 PARIS (France) ! # Tel. : 33 (0) 1 40 51 22 26 # FAX : 33 (0) 1 40 51 22 91 ! # e-mail : services.iers(a)obspm.fr ! # http://hpiers.obspm.fr/eop-pc # ! # Paris, 4 July 2008 # ! # Bulletin C 36 # # To authorities responsible # for the measurement and # distribution of time # ! # UTC TIME STEP ! # on the 1st of January 2009 # ! # A positive leap second will be introduced at the end of December 2008. ! # The sequence of dates of the UTC second markers will be: # ! # 2008 December 31, 23h 59m 59s ! # 2008 December 31, 23h 59m 60s ! # 2009 January 1, 0h 0m 0s # - # The difference between UTC and the International Atomic Time TAI is: - # - # from 2006 January 1, 0h UTC, to 2009 January 1 0h UTC : UTC-TAI = - 33s - # from 2009 January 1, 0h UTC, until further notice : UTC-TAI = - 34s - # # Leap seconds can be introduced in UTC at the end of the months of December ! # or June, depending on the evolution of UT1-TAI.
