IERS Message No. 6
by central_bureau＠iers.org March 19, 2001

March 19, 2001

*************************************************************************** IERS Message No. 6 March 19, 2001 *************************************************************************** IERS' Global Geophysical Fluids Center (GGFC) and Special Bureaus Websites Going to Business The Global Geophysical Fluids Center has made public its official Internet Website <http//bowie.gsfc.nasa.gov/ggfc/>, located at NASA's Goddard Space Flight Center, with an Europe mirror site in Strasburg, France <http//ggfc.u-strasbg.fr> (an Asian mirror site is under preparation). The seven Special Bureaus (SB) can be readily linked. The SBs, under the coordination of GGFC, have the responsibility of supporting, facilitating, and providing services to the worldwide research community, in areas related to the variations in Earth rotation, gravitational field and geocenter motion that are caused by mass transport in the geophysical fluids. The geophysical fluids of the Earth system include the atmosphere, ocean, solid Earth, and core, and geophysical processes associated with tides and hydrological cycles. The time variation of angular momenta and the related torques, gravitational coefficients, and geocenter shift will be computed for all geophysical fluids based on global observational data, and/or products from state-of-the-art models some of which assimilate such data. The computed quantities, algorithm and data formats will be standardized. The results will be archived and made available to the scientific research community. The SBs will maintain individual data archives and services. The Websites are the main conduits for these services.

US/Pacific "double" DST in a few weeks?

leap second news from NIST, ITU/R, etc.
by Paul Eggert March 15, 2001

March 15, 2001

Yesterday Demetrios Matsakis reported on the Leap Second Discussion List some results from an informal session on leap seconds held at the 2001 European Time and Frequency Meeting. He said that the ITU/R committee on leap seconds, which may recommend the abolition of leap seconds, has asked for cooperation from other international bodies, and that the IERS and the IAU are involved. He also mentioned a few other things: * The planned European satellite system Galileo will run on TAI. * NIST is planning to make TAI-UTC available in its WWV series of broadcasts, and it is already available in their NTP format. * NIST plans to do a user survey about this. * Judah Levine of NIST has proposed including the complete list of leap seconds in all NTP packets. Others have suggested just giving the current value plus a change bit. For more about this, please see his full notice, archived on the Leap Second Discussion List (you need to join to to view the archives), at: http://clockdev.usno.navy.mil/archives/leapsecs.html

tzcode2001a.tar.gz and tzdata2001a.tar.gz
by Olson, Arthur David (NCI) March 13, 2001

March 13, 2001

The files ftp://elsie.nci.nih.gov/pub/tzcode2001a.tar.gz and ftp://elsie.nci.nih.gov/pub/tzdata2001a.tar.gz are now available. These incorporate the changes circulated last week on the time zone mailing list by Paul Eggert. There's also an addition to the "leapseconds" file: comments with the text of the latest IERS leap second notice. Trailing white space has been removed from data file lines, and repeated spaces in "Rule Jordan" lines in the "asia" file have been converted to tabs. --ado

TZ Data to XML Project
by Chris Sells March 8, 2001

March 8, 2001

These are the outputs of my attempts to translate the native tz data into XML for easier parsing for applications other than implementations of the standard C routines related to time [1]. This is the first step in a project to merge time zone and map data by the Time Zone Map Group, lead by Chuck Ellis. Chris Sells http://staff.develop.com/csells [1] www.sellsbrothers.com/tools/tz
