I have a couple of lamps in the house on which I use a plug-in timer to turn on around dusk and off at (say) 11.30pm, but of course I have to regularly change the ON time as the time of dusk changes - quite frequently this time of year.
Presumably, this is not that unusual.
Does anyone make a plug-in timer on which one can set the ON time to vary like this (there used to be a crude mechanical device called a 'solar cam' in the good old days). It could operate by detecting dusk as long as the OFF time can be specified.
Any suggestions?
