Class
    Foam::functionObjects::timeInfo
 
Description
    Writes the run time (time-step), cpuTime and clockTime -
    optionally with cpuTime and clockTime change for each time step.
 
    Example of function object specification:
    \verbatim
    time
    {
        type            timeInfo;
        libs            (utilityFunctionObjects);
 
        writeControl    timeStep;
        writeInterval   1;
 
        perTimeStep     no;
    }
    \endverbatim
 
    Where the entries comprise:
    \table
        Property      | Description                         | Required | Default
        type          | Type name: timeInfo                 | yes |
        writeToFile   | Write information to file           | no  | yes
        perTimeStep   | Write value per interval/step       | no  | no
    \endtable
 
    The initial per-step value is likely to be inaccurate and should
    mostly be ignored.
