// 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.

// ----------------------
|

// http://support.microsoft.com/default.aspx?scid=kb;EN-US;q220918
