    I bought an in wall timer switch to control outside lights. The switch has a ground, a common, a hot and a load lead. My standard wall switch has only the black (hot) and white (common) wires. Can this timer switch be used on this circuit?

    If you put in a country location when you registered, we wouldn't have to play twenty questions!

    Is the box that it is going into metallic or plastic?
    Is there a green wire in the box?

    Are the outside lights low voltage?
    If so it maybe the type that typically has a isolated supply and in that case low voltage can be ran without ground.
    If mains powered then you should have a service ground that leaves the timer.

    It is a plastic box. No green wire, just the bare ground wire. It is installked in Florida, USA.

    part number of timer?
    Did you try reading the manual?
    The only thing unclear is the function of the "load line" in the timer..
    Which might be for devices that are downstream of the switch that you don't want on the timer or vice-versa.. Manual should call it out or have a diagram..

    Box-blk is power into the timer. The blk wire? that goes outside to the lights goes to the load terminal on the timer..
    Box-wht is neutral, goes to com side of the timer and to the wht. wire to the outside lights.
    Box-bare is ground, goes to gnd terminal on the timer and to the outside lights.

    If you have no ground wire to feed the outside lights, or they are not fitted with a ground conductor, use a GFI socket for the timer.

    Might be time to brush up on the reading skills..
    All your answers are RIGHT there in the manual under installation instructions section...
    It tells you EXACTLY which wires go where...
