// 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)
