So this number is basically a constant until the next leap second? It seems like ntpd should have a way of knowing, especially when using a gps time source. I did some quick googling and didn't find an answer, but it feels like this isn't a unique problem and someone else should have a solution. And time has always made my head hurt :) Philip > > Regards, > David. > > -- > > > [image: logo_170x100px.png] <http://www.gradiant.org/> > > > > David Zamorano Fernández > Investigador - Desarrollador | Área de Comunicaciones Avanzadas > Researcher - Developer | Advanced Communications Department > > > > Ph.
