Dynamics simulation: Fractional time-step does not work correctly.

[abhyshr]

A time-step of 0.005 works, but not 0.008333 with dynamics simulation.

Need to check whether this is an issue because of rounding. For example, if the fault on time is 1.0 and the time-step is 0.08333, then the step number calculation 1.0/0.08333 will have some rounding error which may prevent the fault from applying..Not sure, need to check.
