Not well indexed? That's putting it mildly.

Here's an example of use (MUCH needed in Help):

Export["test.tsv",
   {{"2005-01-24", "2005-02-14"},
     {"2005-01-24", "2005-02-14"}}]
Import["test.tsv",
     ConversionOptions -> {"Numeric" ->
       False, "DateStyle" -> "American", "DateSeparator" -> "-"}]

No matter what options are used, however...

Why is the second record converted differently than the first?
