BI publisher batch job - why not real interval in minutes frim the start?

Hi,

We are using BI Publisher with Primavera for reporting.

With hours as interval: If I set a staring time e.g. (date) 09:03:33 and the interval as one hour, the report will be fired every hour xx:03:33.

With minutes as interval: all the report will fire at full hour (xx:00:00) and then set of minutes past the full hour, e.g if I have a value 23 minutes, the report will be fired xx:00:00, xx:23:00, xx:46:00, xx:00:00...etc.

When I have a lot of memory consuming reports and I want to run them at minutes Interval, it will be difficult to avoid the full hour overload.
