Another addition to Falsehoods programmers believe about time. A scary one.

You lose GPS, which breaks real-time power grid management

Why? Power infrastructure isn't moving, and ntp is plenty accurate enough for timekeeping here; no need for GPS clocks.

Aren't transformers protected these days? I thought they had all been outfitted with automated safety disconnects ages ago pretty much everywhere. Obviously most transformers going offline all of a sudden is still a pretty scary situation, but recovery should be on the order of days, not months.
