Not shown on the graph, but the offset due to a CPU-heavy task (recompiling NTP from source, taking about 25 minutes) resulted in a 20 s positive excursion, followed by a 10 s negative excursion as temperatures cooled and NTP recovered.
When using a u-blox MEO-6M GPS module, with its PPS pin connected to the GPIO 24 pin for a kernel-mode "ATOM" ref-clock, similar results are obtained.
Zero offset corresponds to the middle line of the graph, as the utility I use is incapable of plotting negative values.
I therefore add half the Y-axis range to the actual values before plotting.
If you want to get started quickly, with the best results for minimum fuss, please see my Raspberry Pi NTP quick-starter page.
Please also see that page for issues with the Jessie release of Linux, and with the newer Raspberry Pi model 3.
Offsets are reported to be with about /-5 milliseconds (and therefore off-scale once on the graph below).
The four-line Changing to a tight coupling to a local stratum-1 server on the LAN produces much better results, with timekeeping in the order of 30 microseconds.
As an experiment, I purchased one of the low-cost credit-card-size Raspberry Pi computers, and have configured it to run NTP (Network Time Protocol).Tags: Adult Dating, affair dating, sex dating
