Getting incorrect list of scheduled reports

Hi Eveyone

I want to find the list of reports that are scheduled to run on a particular day.

I am executing the following query:

select * from ci_infoobjects where si_recurring=1  and si_instance=1 and  si_nextruntime='2014.06.13'.

This should give me the list of all reports which are supposed to run on 13TH June 2014.

However i am not getting all the reports instances which are supposed to run that day.

I have used si_nextruntime and i have observed that it returns inconsistent results.

Please guide me on this.
