Not sure if correct as the acronym isn't familiar with me, but the mention of clocks leads me to think it is about the experiment of the release of regulation of the POCOs and or generator station from maintaining the grid to a base frequency and how it has affected our clocks.
Click here for more info
The idea of the test is to see if the grid can be better stabilized without the rock solid frequency having to be maintained, this allows for better load regulation at each generator station as load is a function of frequency on the generator, if the generator speed in increased the load is increased as the generator tries to lead the grid if the speed is slowed it decreases the load on the generator as the frequency is lagging the grid. hope that helps.

If I am on the correct subject then my answer to the OP is no it hasn't affected any of my own clocks as the ones I have are battery backed up and have it own reference crystal as a reference, but if we are going to see it it will show up in our simple time clock we use on lighting as these have synchronous motors in them that do use the grid frequency to maintain time, very few clocks of today use the grid for a reference, but the good ole Intermatic mechanical time switch's still do like the T-101-104s and many others

Great. Now I've got to buy a new watch. I'll have to check with the dealership next week to see if they have a fix for the clocks in my vehicles. What about the billions we have invested in the GPS satellites orbiting the Earth? They are going to cost us billions with this little experiment. :rant:

GPS is a real problem
GPS is a real problem
It's my understanding that the GPS satellites use 60Hz over North America, 50Hz over Europe.
So now that the North American Grid frequency can drift, will we need to go to Europe just to know where we are?

Why on earth would GPS be locked to hz?
The time signals are internal to the GPS system not connected to the grid.

Not to mention that the Earth is slowing down and the continents are drifting so we are in a constant state of flux. Oh the horror!It's my understanding that the GPS satellites use 60Hz over North America, 50Hz over Europe.

I guess I missed the joke.

But once the Space Elevator is in place they will be connected to the grid. The higher velocity objects in space experience a different time so they will have to be coupled through the Heisenberg Space-Time Conversion Module (pronounced HESP-COM for short).

And caused me to waste another perfectly good post since I did not catch your post in time. Must be the grid.
Sorry, I was hoping someone knew right off the bat. Two Way Automated Communication System. (TWACS) it is an automated meter reading program that sends us readings through low frequency power line communications.
This signal rides along on the 60 hZ wave right at the zero crossing.
When the signal puts a small load on the line for reading, apparently the tiny blip in the wave causes digital clocks to speed up because the clocks count this when they convert to square wave for the counter to use.
Had a customer call in to report his clocks are gaining about five minutes a week. Just curious if anyone else has run into this problem.

Why didn't you just say "smart meters"?:?
There are a few different kinds, and not all transmit the same. TWACS is a PLC (power line carrier) system. Others use radio frequency and wouldn't affect clocks. Plus, you say smart meters and some want to start in on the fabled health hazards.:lol: Sorry for any confusion.

Since one was put on the side of my home my hair has gone gray and I have more lines on my face, it must be the smart meter. I won't even go into what it has done to my wife.

I never run into a T-101 that has correct current time on it - I am usually resetting them to current time if I am involved with one. I don't think it is as much the T-101 is inaccurate as much as power has been lost at times and it is just off.
The GPS satellites all have really long extension cords and are connected to commercial power systems at the surface. If GPS service goes down it is usually because an airplane went through restricted space and pulled the cord out of the receptacle:lol:
