Daniel,
I've placed two log files for you under http://leapsecond.com/pages/mains/
log1932.dat.gz -- timing of every 60 Hz zero-crossing (1.296 million samples)
log97312.dat.gz -- timing of every 60th zero-crossing (21.6 thousand samples)
Each represents 6 hours of collection time. Units are seconds (elapsed time),
resolution is 100 ns, granularity is 400 ns. This data was collected with a
picPET (http://leapsecond.com/pic) using an accurate 10 MHz reference.
This isn“t very clear to me. First few lines say:
0.0000000
-0.0000029
-0.0000071
-0.0000064
0.0000027
-0.0000099
-0.0000176
Time went backwards?
Daniel
