Time reporting has float error

Hello, I'm running the development version.
The reported time presents variations in small decimal numbers, I'm wondering if that is the real time of the simulation or if it is a floating point approximation. I imagine the latter since the timestep is an integer number.

The script I'm running:

protein = openfe.ProteinComponent.from_pdb_file(protein_file)
solv = openfe.SolventComponent(ion_concentration=0.15 * unit.molar)
simulation_system = ChemicalSystem({"solvent": solv, "protein": protein})
md_settings = PlainMDProtocol.default_settings()
protocol = PlainMDProtocol(md_settings)
dag = protocol._create(
    stateA=simulation_system, stateB=simulation_system, mapping=None
)
protocolRunner = dag[0]
result = protocolRunner.run()

Start by tracing the time values produced after PlainMDProtocol.default_settings(), protocol._create(), and protocolRunner.run(). Compare the reported timestep and time calculations with the displayed CSV values, then determine whether the observed floating-point variation is expected or indicates a reporting bug.
