I finally fixed this issue with this cset (http://hg.savannah.gnu.org/hgweb/octave/rev/ee34028f63fc). The case of spacing by months had a similar issue which I also fixed.

Closing report.

I confirm this behavior for 3.6.2. The problem is around line 195 of datetick.m. The separation sep is computed from minyear and maxyear (line 189), but the ticks are computed from the corresponding datenum. But, because of leap years (I think), the original separation (20 in this case) is lost. So, the ticks should be computed in the same if branch.

I think a similar problem should occur when computing separations between months (previous if branch).

This example

produces dateticks ...,1699, 1720,... (instead of ..., 1700, 1720, ...).
