Class
    Foam::functionObjects::stopAtClockTime

Description
    Stops the run when the specified clock time in second has been reached
    and optionally write results before stopping.

    The following actions are supported:
    - noWriteNow
    - writeNow
    - nextWrite (default)

    Examples of function object specification:
    \verbatim
    stop
    {
        type        stopAtClockTime;
        libs        ("libutilityFunctionObjects.so");
        stopTime    10;
        action      writeNow;
    }
    \endverbatim
    will stop the run at the next write after the file "stop" is created in the
    case directory.

Usage
    \table
        Property | Description              | Required | Default value
        type     | type name: stopAtClockTime | yes    |
        stopTime | Maximum elapsed time [s] | yes      |
        action   | Action executed          | no       | nextWrite
    \endtable
