// MSSQL returns dates with the format Oct 13 2002 or 13 Oct 2002
// and this causes tons of problems because localized versions of 
// MSSQL will return the dates in dmy or  mdy order; and also the 
// month strings depends on what language has been configured. The 
// following two variables allow you to control the localization
// settings - Ugh.
//
// MORE LOCALIZATION INFO
// ----------------------
// To configure datetime, look for and modify sqlcommn.loc, 
//  	typically found in c:\mssql\install
// Also read :
//	 http://support.microsoft.com/default.aspx?scid=kb;EN-US;q220918
// Alternatively use:
// 	   CONVERT(char(12),datecol,120)
//
// Also if your month is showing as month-1, 
//   e.g. Jan 13, 2002 is showing as 13/0/2002, then see
//     http://phplens.com/lens/lensforum/msgs.php?id=7048&x=1
