49 Hz is impossible. It would mean that a clock using this frequency would be slow by more than a minute per hour. Long-term accuracy is extremely high, precisely because clocks depend on it. And since almost all of Europe is interconnected, adjusting the frequency must be a _very_ slow process. So errors of 2 percent really can't be tolerated. Ciao, -- FA O tu, che porte, correndo si ?
