Half a microsecond / day!
And suitable for embedded devices / applications.

Now, how does that accuracy / repeatability and precision compare with the range of jitter specs measured on current consumer digital devices?
Is CD or DAC jitter in PPM or ???

Using the broadcast WWV / WWVH signal in a home situation is generally impractical, though I know of the in-home 'atomic clocks' with built in receivers. If you live in the wrong place, using WWV becomes less than practical.
WWV is what? 10KW or maybe 25KW? Even with a good SW receiver I am sometimes not able to get a good, stable signal at any frequency from 5Mhz to 20Mhz. I'm not sure about lower fequencies.
I've even logged WWVH from the Hawaiian islands....You can sometimes hear it during the planned downtime of WWV which still comes from Ft.Collins, Colorado.

Too much is never enough
