Description of problem:
I would like to advance the period date on a task automatically.
e.x a task should send mail every 1 week on a report displaying data from 1/1/2012 until 31/1/2012

When CURRENT_DATE is March, the report will automatically know this thus :
its period date will be ->
1/2/2012 until 29/2/2012

So the function should be
1/ (current_timestamp - interval '1 month')/2012 
until 29/current_timestamp/2012

Version-Release number of selected component (if applicable):
ovirt-reports 3.0
rhevm-reports 3.0.2-2

How reproducible:
always

Steps to Reproduce:
1.create task to any report
2.define in criteria filters the date if its a month than
 -select Value displayed as "CURRENT_DATE"
 -if its a range than since 1/x/20xx until "CURRENT_DATE"
  
Actual results:
User needs to change all its tasks manually to be updated as he pleased

Expected results:
Should do the above automatically - no user intervention
