There is a danger in only having one standard, no matter what that standard is. Depending on -new-, -cutting edge- technology without a back-up is also very foolish. Another face on this thing is how many other places/nations/countries use WWV? What do they do if it disappears? "Just up-grade!", right? Easy to say, maybe not so easy to do. Okay, here's the obligatory 'cheap-shot'... You wanna get rid of WWV 'cuz it's -OLD-! Just another one'a them ol'farts, right? And just like those ol'farts, they are old because of a good reason... think about that.
