[ncl-talk] minor tickmarks in date/time style plot

[ivica]

Got it with some additional effort.
If someone needs this is how I did it:
   utc_date = cd_calendar(time, 0)
   year   = tointeger(utc_date(:,0))
   month  = tointeger(utc_date(:,1))
   day    = tointeger(utc_date(:,2))

   start_month=ind(day.eq.1);
   start_year =ind(month.eq.1 .and. day.eq.1)
   tmp = dimsizes(start_year)
   nyears = tmp(0)

   res at tmXBTickStartF  = start_year(0)
   res at tmXBTickEndF    = start_year(nyears-1)
   res at tmXBMode        = "Explicit"
   res at tmXBValues      = time(start_year)
   res at tmXBLabels      = year(start_year)
   res at tmXBMinorValues = time(start_month)
