// Use the DateOf and DtOf methods to load Chilkat date/time objects with the date/time values.
// The CkDateTime object is primarily for loading a date/time from numerous formats, and then getting
// the date/time in various formats.  Thus, it's primarly for date/time format conversion.
// The DtObj object holds a date/time where the individual components (day, month, year, hour, minutes, etc.) are 
// immediately accessible as integers.
