Jeff,
in RPL mode enter HH <space> MM <space> SS <Custom Function>.
If your custom function has been built with (say as an example)
DEFINE('K(h,m,s)=h*3600+m*60+s')
in algebraic mode (which I suppose, because of your question), calling your custom function as described above will solve the RPL equation:
<< -> h m s 'h*3600+m*60+s' >>
and display the expected result.
For a description on DEFINE see Chapter 3 of the User Guide (the large pdf document on CD).
For a more user-friendly implementation, pls. look up the fine descriptions of - '30 MENU' usage in equations - to build custom menus. A lot of sophisticated samples of this technique are available at

Hope this helps!
