How are you collecting the data? What's the time between samples? One possibility is that one system is picking up extra clock ticks. If your data is dense enough, that should be pretty obvious if you zoom in on the graph. Here is an example: http://www.megapathdsl.net/~hmurray/time-nuts/60Hz/60Hz-g3.png That's sampling every 10 seconds. Glitches like that are easy to spot if you plot the frequency. It's the difference in counts divided by the difference in times between a pair of samples. At 10 second sampling rate, you get 600 counts per sample. 601 counts turns into 60.1 Hz. That 0.1 Hz is well above the noise. (at least with my setup) -- These are my opinions, not necessarily my employer's.
