Date: Tue, 25 Nov 2003 16:28:15 +0100 Message-ID: <009001c3b368$be96cb30$e57f68c1@TAI20> Importance: Normal Sender: owner-igsmail Precedence: bulk ****************************************************************************** IGS Electronic Mail 25 Nov 07:27:58 PST 2003 Message Number 4725 ****************************************************************************** Author: Jim Ray In the November 2003 issue of "GPS World" on page 12, the piece entitled "Leap Second May Affect Some Units", the first paragraph is wrong. There will be no leap second insertion into UTC, neither on 27 November nor 31 December nor any other forecast epoch. Leap second decisions are made solely by the International Earth Rotation and Reference Systems Service (IERS), specifically by the EOP Product Center at the Observatoire de Paris. Please refer to the website at: http://hpiers.obspm.fr/eop-pc/ The actual problem is one of certain receiver firmware and was described already in IGS Mails #4679 and 4717.
