David,
Treating solar time as an hourly time/frequency reference over one year, attached are:
1) eot-phase.gif -- phase plot (time error); the usual equation-of-time plot you see everywhere.
2) eot-freq.gif -- frequency plot, essentially the variation in length of "solar second".
3) eot-adev.gif -- the ADEV of a clock keeping solar time.
This data came from http://leapsecond.com/tools/eot2.c (I agree there are more complex and more accurate equation of time calculations, but this is good enough for ADEV).
