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.
