Tom, I don't intend to challenge your knowledge but to discuss the subject. It's amazing what a different viewpoint can do, and how difficult it is to share viewpoints in email.
As a person who grew up with synchronous clocks, when real men used vacuum tubes, I find it incredible that a lightly loaded synchronous clock motor could go any faster than the line frequency. It can go slower if the bearings gum up with old oil and the motor drops out of sync. That's why I say that the reference clock slowed down. We can't resolve this until we know what Yukon was using for clocks. I thought the article implied that their reference clock was a wall clock somehow driven by some signal from some satellite. GPS wasn't mentioned.

It reads to me like their line clock malfunctioned and was running fast *when it had no cause to*, so they responded as expected (slow the generators), with the expected result (everyones clocks slowed down). > The satellite clock was slow. Yet my takeaway from the article was not that the satellite clock was in error, but that the line clock was. It was running fast when it shouldn't have. I can see where a line clock would run fast when it shouldn't, but I can't see where a GPS clock would run slow...
