Look up the function DateList[].  The problem is that 10/1/04 means
October 1, 2004 in the US and January 10, 2004 in (for example),
Denmark.  Mathematica is warning that the format you are using is
ambiguous, but it is going ahead and assuming you are in the US and
giving you a result (which may not be what you intended if you happen
to live in Copenhagen.)

To disambiguate, wrap your date strings in a DateList[] function of
the form:

In[22]:=
DateList[{"10/1/08", {"Month", "Day", "Year"}}]

Out[22]= {8, 10, 1, 0, 0, 0}
