interval EsriTimeDelta  and modifying the interval????

Discussion created by cgarlock on Apr 3, 2013
In the help it says that the timeStepInterval for a layer is read only, and EsriTimeDelta is read only,

Therefore, how can you modify an interval if you cant have write access? 

This link:

states that currentTime and endTime as well as the interval can be modified.
Is changing the interval really posisble if an interval is already established in a layer and dataframe?
