The acquisition times are not saved in the NIfTI headers, but you can read
them from the original DICOM.  You can read the DICOM headers via:

P=spm_select(Inf,'.*','Select DICOM files');
H=spm_dicom_headers(P);

Then you can see what's in them by (for example):

H{1}

To see all the dates and times, you could try this:

for i=1:numel(H),
    fprintf('%s\t %d-%d-%d\t%s\n', ...
             H{i}.SeriesDescription,...
             H{i}.SeriesNumber,...
             H{i}.AcquisitionNumber,...
             H{i}.InstanceNumber,...
             datestr(H{i}.AcquisitionDate...
                   + H{i}.AcquisitionTime/(24*60*60),0))
end
