The interesting thing is that they have been seriously thinking

Indeed. In Sweden that has become a big thing, with the deregulated market we
have. We haven't chosen that path here at home yeat, but I guess it is a
question of time like everything else.
In Denmark they charge you $1000 extra to get a three-tariff meter :-(
Here in the UK we have "Economy 7" (it should be renamed "Rip-off 7")
where electricity is sold cheaper overnight. As far as I know, there is
no installation fee for that, but if you have "Economy 7" you pay more
for electricity during the day. So unless you make heavy usage overnight
(as one does with electrical storage heaters), it is not a good idea.
My meter, uses a clock that used to keep accurate, but which is now
usually wrong.
Whether the meter uses the 50Hz for timing I do not know, but there is
battery in there too. It may be wrong since the battery has failed and
so the clock stops when there is a power failure, or it might be low in
voltage which means the clock runs slow.
But here at least, there is nothing very clever about how the time on
those clocks is kept. Which suits me, as sometimes I get electricity
cheap during the day now!
