Hi Mark,

FWIW, on v5.0, I can't reproduce your problem yet.  Here is what I get:


In[1]:=
Export["test.tsv",
     {{"2005-01-24", "2005-02-14"},
     { "2005-01-24", "2005-02-14"}}]
Out[1]=
test.tsv

In[2]:=
!!test.tsv
>From In[2]:=
2005-01-24	2005-02-14
2005-01-24	2005-02-14

In[3]:=
Import["test.tsv"]
Out[3]=
{{2005-01-24,2005-02-14},{2005-01-24,2005-02-14}}

In[4]:=
$Version
Out[4]=
5.0 for Microsoft Windows (June 10, 2003)
