    Serialize a setTimestep command using FlatBuffers.

    Parameters
    ----------
    builder : flatbuffers.builder.Builder
        The FlatBuffers builder instance which serializes data. If this
        parameter is None, then a new builder will be created
    label : str
        The label of the timestep to select in SEAScope

    Returns
    -------
    tuple(flatbuffers.builder.Builder, int)
        A tuple which contains two elements:

        - the :obj:`flatbuffers.builder.Builder` instance which has been used
          to serialize data
        - an :obj:`int` which is the address/offset of the serialized object
