No worries.

If they use a fine tooth wheel with a ratchet, I can see it skipping

Exactly, so I sent the paper the following email:


Your recent article about clocks running slow in your area was quite  
interesting, but as an electrical engineer, I found it rather confusing.

If time permits, would you mind explaining exactly what went wrong  

Did the line clock they use as a power line reference actually run  
excessively fast when it had no reason to?

Or did the GPS referenced clock they follow run slow?

Whichever is the case, do they have any idea what actually went  
wrong?  I do understand the part about adjusting the generator  
frequency, and how that can make everyones clock run slow; what I am  
having difficulty grasping is how their display/reference equipment  
malfunctioned to cause the misunderstanding in the first place.

Thank you very much for your time and kind assistance.
