That's what they're doing here, opting to skip "patching" the time
error. They're not ignoring frequency altogether, but rather only
minding that aspects that have to do with grid stability, not your alarm
clock. This is for the better anyway, and NTP/GPS/WWV/WWVH is the way
to go to keep clocks accurate and hopefully will be the outcome of any
consumer complaints.

I've seen conversation in various forums and lists I read that they are
going to ignore or not care about the 60Hz standard. This is incorrect.
They just aren't going to purposely deviate from the scheduled
frequency to perform manual TEC.

Mind you, that they still care about why the frequency is off, and when
things are not able to quickly compensate, they want to know and be able
to pinpoint it and fix it:

Specifically, read this PDF:

Thank you, Jason.  I did some searching before I posted that, to see if
I could locate better information, but clearly, I didn't search hard enough.

Cheers,
