; check if new additional time steps should be added to the data_l2_x array
;
; 2016-05-03: CMF: modification to routine for spectra packets. You must set type to 'spectra'. This prevents time stamps being added that are too close together
;                  in time that are identical time steps. This only affects spectra. Do not set type at all for other products - the routine will use the old method in this case.
