TTimeField encapsulates the fundamental behavior common to fields that contain time values. Time fields contain time values (without any date), which they manage using the TDateTime type (Delphi) or class (C++). 

If you use the Fields editor at design time to create a persistent field component for the time field, you can access it by name at runtime. When using dynamic field components, you can access the TTimeField instance using the dataset's Fields property or FieldByName method.
