Description

TDateTimeField is the class used when a dataset must manage data of type datetime. (TField.DataType equals ftDateTime). It also serves as base class for the TDateField or TTimeField classes. It overrides some of the properties and methods of the TField class to be able to work with date/time fields.

It should never be necessary to create an instance of TDateTimeField manually, a field of this class will be instantiated automatically for each datetime field when a dataset is opened.
