cannot specify no times

with utilities such as foamToVTK, surfaceMeshTriangulate etc, there is no normal way to select only the constant time. Eg,

foamToVTK -constant

Includes constant as well as all other times.

foamToVTK -constant -time none

Warns about "Bad scalar-range", but has the desired behaviour. Selects constant, but nothing else. Can use other hacks for this as well, Eg, -time '' or -time , etc, but these all look like a workaround.
