PSCs endpoint - event timepoint

PSCs - persons-with-significant-control-statements
I am trying to fetch data for PSCs , its been 4 days there is no data from this endpoint.
I need atleast relevant EVENT TIMEPOINT for this particular endpoint to start fetching the data.
The timepoint need not to be latest one, any timepoint which is relevant/sample for this PSCs would be helpful.
Even sample json response will be much helpful.
