Because there are millions of software updates that will have to be made, schedules to be changed, etc. Will take some time.
i never thought about that angle. thanks for pointing that out.
and as was mentioned, probably another Y2K moment for some folks.
I don't know about mainframes, but for windows all they have to do is delete the applet that tells it to change the time on whatever date it is. Everytime they've changed the DST implementation date, MS and all the linux distros incorporate the change into their regular updates. Our Durango and 300 get their time from the GPS satellites, I think? No idea what's involved with that.
