NullDate constant
Represents a TDateTime type without date and time values.
Declaration
NullDate: TDateTime = 29584650.5Description
NullDate is actually a writeable constant. This is used for
compatibility reasons. It is however a bad idea to change the value to
anything that is an actual date that is withing the range for the TDateEdit
control.
The value was modified in LCL version 3.0.
