The function etime (elapsed time in seconds) returns an error when you
compare times with different years. From the code

if (t1 (1) != t0 (1))
   error ("etime: can't handle timings over year boundaries yet");
endif

Is that because it's painful to deal with leap years? What's the best fix?

(1) Write a separate function to find if a year is a leap year.
(2) Determine if a year is a leap year inside etime.
(3) Bring over datenum from octave-forge and modify it to handle leap
years and then use it for year, month, and day differences but not
fractional parts of days.
