Bug & Fix :
Fieldtype : TimeStamp
Property Format : HH24:MI
read and write with smartquery :
smartquery.fieldbyname ( 'yx' ).AsdateTime := Value;
field-content and result in visual controls
' ....00:00' -> '...01:00'
' ....01:00'- > '...02:00'
"Fix"

:
procedure TDModuleDP.pFIBDSTermineDES_TIME_ENDGetText
(Sender: TField;
var Text: String; DisplayText: Boolean);
begin
Text := FormatDateTime ( 'HH:NN' , Sender.AsDateTime );
end;
