Problem parsing date formats using Import

I'm trying to parse a file which has dates in the format YYYYMMDD,
e.g. 20080101. However I just can't seem to get the DateStringFormat
to work - it works fine for YYYY-MM-DD or YYYYMM-DD but not if I
remove the separators entirely. Is this because of the ambiguity
between numeric and this date format? Does the automatic date parsing
not work for entirely numeric date formats?

Thanks and regards,
Jon Rowland

In[137]:= ImportString["1982-04-22\n1982-04-23", "Table",
"DateStringFormat" -> {"Year", "-", "Month", "-", "Day"}]
Out[137]= {{{1982, 4, 22}}, {{1982, 4, 23}}}

In[138]:= ImportString["198204-22\n198204-23", "Table",
"DateStringFormat" -> {"Year", "Month", "-", "Day"}]
Out[138]= {{{1982, 4, 22}}, {{1982, 4, 23}}}

In[139]:= ImportString["19820422\n19820423", "Table",
"DateStringFormat" -> {"Year", "Month", "Day"}]
Out[139]= {{19820422}, {19820423}}
