Converts standard XSD date formats to characters suitable for output.

string ms:format-date(string datetime, string format [,locale])

Parameters

string format
Contains a format string, according to Win32 API GetDateFormat functions.

locale [optional]
Defines the locale to format the data for (for example, "EN_us").
