Philip,

The bug is listed on the 3.8 Bug Fix list
(http://wiki.octave.org/3.8_Bug_Fix_List), however it's not listed as an
official gating item for the release.  I took a quick look at it, but I
don't spend much time with gnuplot so I don't have a good answer.  The
problem is not with datetick, but rather with how the command "set (gca,
'xticklabel', ...)" works.  Instead of just overwriting the existing
labels, this is apparently invoking the auto-axis labeling routine.  Simple
code to reproduce:

plot (1:4)
## At this point labels are 1, 1.5, 2, 2.5, 3, 3.5, 4
set (gca, 'xtick', 1:4)
## At this point labels are 1, 2, 3, 4
set (gca, 'xticklabel', {'A', 'B', 'C', 'D'})
## Now labels are 'A', 1.5, 'B', 2.5, 'C', 3.5, 'D'
