- Time is normally constructed with READ_MODIFIED for its controlDict
  and objectRegistry, but for certain applications (eg, redistributePar)
  it can be useful to construct without file monitoring and specifying
  MUST_READ instead.

  Example,

  Info<< "Create time\n" << Foam::endl;
  Time runTime
  (
      Time::controlDictName,
      args,
      false,   // Disallow functionObjects
      true,    // Allow controlDict "libs"
      IOobjectOption::MUST_READ  // Instead of READ_MODIFIED
  );
