Why not just use xtickv and xtickname to put the labels you want, where you want, called what you want.

years=indgen(10)+2003
xtickv=julday(1,1,years,0)
xtickname=string(years,format='(i4.4)')
plot, time, data, xrange=julday(1,1,[2003,2013]), xtickv=xtickv, xtickname=xtickname, xticks=n_elements(xtickv)-1

or similar
