    I am trying to plot a hovmoeller plot by reading a netcdf daily datafile
    and would like to have the time axis labelled with dates like "20031120"
    or something like that.

    I could not find specific information online, I would appreciate help or
    directions to online instructions. below I include a test script.

    Thank you,

    load "$NCARG_ROOT/lib/ncarg/nclscripts/csm/contributed.ncl"


       a = addfile("/Datasets/ncep/hgt.2003.nc","r")
       x = a->hgt(:,{850},{60},:)

       wks = gsn_open_wks ("ps", "test" ) ; open ps file
       gsn_define_colormap(wks,"BlWhRe") ; choose colormap

       res = True ; plot mods desired
       res@cnFillOn = True ; turn on color fill
       res@gsnSpreadColors = True ; use full range
    of colors

       res@trYReverse = True ; reverse y axis

       res@lbLabelAngleF = 45 ; angle labels

       plot = gsn_csm_hov(wks, x(:,{0:360}), res)
