I have an old clock/radio/alarm that even picks up the atomic clock signal but that does not seem to work for DST and it certainly does not recognize the new dates for chaning DST. So I had to change the clock on Sunday, and it will change the time the usual, first Sunday in April and the last Sunday in October. That means I will have to set the correct time again. 4 times a year !!
The worst part is that I don't think this is saving us any energy, and not worth all the trouble !!
