FVWM: Fwd: How to make xclock transparent?

[for.register for.register]

Hi, all

 Is it possible to make xclock transparent?

 Here is my config, it doesn't work.
 Colorset 8      RootTransparent
 Style  XClock   !Title, !Borders, Colorset 3, NeverFocus, \
                           WindowListSkip, CirculateSkip, StartsOnPage 0 0, \
                           Backcolor Colorset 8
 DestroyFunc StartFunction
AddToFunc StartFunction
        ... ...
        + I Exec exec xclock -digital -chime -twelve \
                      -strftime "%A %b %I:%M%P (%j) of %Y"
        ... ...

Thanks/Walter
