Yes, and the one in my sleeping room too. This morning both were walking 2 or 3 minutes behind my DCF77 in the computerroom. So I correct them to at least one minute above the DCF77 one.

I tought the ac~ Voltage was/is also an indicator for that. When you want to feed in power to the grid from your dc=/ac~ inverter of your sunpanels, its Voltage has to be higher to let the Amperes flow ;-). If many do that the ac~ Voltage is going on higher at sunny days, then in the evenings. At night the power demands are lower, so the ac~ Voltage is going up again until the next morning if everyone is making thee and coffe etc. Many years in Belgium they led the light on at highways the whole night because the nuclear power plant was hardly to reduce its power. To the common public this behavior was strange to the enviroment.
You know that even the pause in footbal games can be seen on many nets? More water for the toilets and more electrical energy for coffee etc.
