Class
    Foam::functionObjects::time

Description
    Writes run time, CPU time and clock time
    and optionally the CPU and clock times per time step.

    Example of function object specification:
    \verbatim
    time
    {
        type            time;

        libs            ("libutilityFunctionObjects.so");

        writeControl    timeStep;
        writeInterval   1;

        perTimeStep     no;
    }
    \endverbatim
