Time-Variable

Hello, I am looking for the possibility to save a time, like '10:00:00', into my db, the only variables, as I know, for those questions are DateTime or Date, isn't there a simple Time -Var ? Or how do I get rid of these stupid date at the beginning of the DateTime, I have to set, even if I tell the db DateTime Hour To Second. We are using Online 7.22 (Aix). MfG Torsten Kleine B'ning
