[time-nuts] Re: Power line timing -- setting a clock

[Walt]

Good morning, Larry,

Just wanted to let you know that I observed my line-controlled clock being
17 seconds behind this morning.   A quick glance at
https://fnetpublic.utk.edu/frequencymap.html showed that the WECC frequency
was hovering around 59.95 at the time.  Since this website doesn't offer
historical data, who knows what the trend could have been in the last 9
hours since I last happened to look at my clocks.

I'm not yet set up to record the line frequency here - too many other
projects on the table.  But I do watch the delta between my Heath and GPS
time, and since you first brought up the issue, it's usually been within a
few seconds.  This morning's event is quite unusual.

Cheers,
Walt
