Description

TDateTimeField represents a date-time field in a dataset.

TDateTimeField encapsulates the fundamental behavior common to Date-time fields. Date-time fields contain combined date and time information, sometimes called timestamps. TDateTimeField introduces new properties to convert between date-time values and other data types, and to format the value of a date-time field for display.

Note: Date-time values accessed through dbExpress use TSQLTimeStampField instead of TDateTimeField

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