I am working with K2 BlackPearl v0803.  I have a need for a workflow to commence at the start of every month. 

What are the best practices for this requirement. 

Do I need SmartObject's for this?

Can I get away with running a SQL Server Scheduled Task/Job and based on this event, trigger the workflow?  Essentially have the workflow wait for an event?

 Any assistance would be great.
