Year 2005 will last a second longer

The International Earth Rotation and Reference Systems Service (IERS) has announced the insertion of a positive leap second into UTC at the end of December 2005.
• UTC has been defined to assure that, on average over the years, the Sun is overhead within 0.9 s of 12:00:00 UTC on the meridian of Greenwich. To preserve this tolerance, leap seconds have been introduced in UTC since its adoption in 1972. No leap seconds have occurred since 31 December 1998.
• The next leap second will be introduced after the last second of 31 December 2005. Following that, and until further decision of the IERS, the difference between International Atomic Time (TAI) and UTC will amount to 33 s (TAI – UTC = 33 s). – More information can be obtained from the IERS site

Special issue of Metrologia to celebrate fifty years of atomic time-keeping

The summer of 2005 marks the fiftieth anniversary of the experiments of Essen and Parry at the NPL (Teddington, UK) which resulted in the first caesium beam atomic frequency standard, the first operational atomic clock. To mark this anniversary, a special issue of Metrologia has been published (Volume 42, number 3) with Dr Terry Quinn CBE FRS as Guest Editor. Dr Quinn has assembled a collection of papers that detail not only the original atomic clock of Essen and Parry but also many aspects of the development of atomic timekeeping over this last half century. – Browse

Potential economic impact of the CIPM MRA

On behalf of the BIPM, a study was carried out by KPMG Consulting with three main goals:

to study the economics of central coordination of multilateral relationships between individual national metrology institutes (NMIs);

to study the MRA's potential impact on economic efficiency as a facilitator of reductions in technical barriers to trade; and

to present a set of arguments that might be useful in ensuring that potential economic benefits associated directly with the MRA are actually realized.
