Here's what I get:

    $Version
5.1 for Microsoft Windows (October 25, 2004)

    Export["test.dat", {{"2005-01-24", "2005-02-14"},
    {"2005-01-24", "2005-02-14"}}];

    Import["test.dat", "Text"] // InputForm
"2005-01-24   2005-02-14\n2005-01-24   2005-02-14"

    Import["test.dat"]
{{"2005-01-24", "2005-02-14"}, {2005, -1, -24, 2005,
    -2, -14}}

Rather than a bug, the behavior originally cited would seem to be a 
failure of the documentation to describe the default behavior of Import 
when the file extension is ".dat".
