Daylight savings seems to be a bit archaic especially with modern flexible
working practices. Why not fit the working day around the clock seasons,
rather than try to correct things twice a year?

I'll do my best to be polite.
Daylight savings is more beneficial the further from the equator you
go. I love it and would never want it to go. As pointed out, this is a
local issue. Go lobby your local representative.

Thanks for the replies!
This is an interesting example of no two oscillators are the same.
I certainly expected that there would be aging and retrace on a cold
oscillator, but I started both Z3801As almost simultaneously and within
