I need to accumulate data from several countries with different date-format
than US. Like some send us the .txt files with following data:

-------File1.txt-----------------------------
Actual Data: 1/1/2004 Account Open
Translation: 1/Jan/2004

Actual Data: 8/12/2004 Account Closed
Translation: 8/Dec/2004
--------------------------------------------

-------File2.txt-----------------------------
Actual Data: 1/1/2004 Account Open
Translation: 1/Jan/2004

Actual Data: 8/12/2004 Account Closed
Translation: 12/Aug/2004
* as per their regional date settings

Actual Data: 8/13/2004 Account Closed
Translation: 13/Aug/2004
* as per their regional date settings

--------------------------------------------

Now If I import / copied the data of both files into Excel, MS Excel using
my date regional settings tanslate both dates in d/m/yyyy so i get only one
date i.e. 8/Sept/2004.

Even manually its hard to guess that which date-format is used in File2, but
after looking at series of dates one can found what date format has been
used.
