In the UK Im not aware of any change to the 50hz stability yet, as
recently as 2002 we got an order for a "work alike"
clock for shop display and was given a clock module to copy, the clock
chip being obsolete I just used a PIC and did nearly all the work in
software instead. I have seen them in the wild still working in corner
shops, long live mains stability.
We were a clock company so were repairing old mains motored mechanical
clocks to0, they had kept running from the 1950's and 60's. The method
just works.
I did visit a power stations and the timing was mentioned.
It is enshrined in law and a public graph of our stability
