AOW: condition date=NOW

I am using a SuiteCRM 713 with AOW.
I am not able to make a workflow work with the condition datefield=NOW. Could you please explain how it works? I need to set a date in the future in a module when the workflow will have to run and send an email.

You can add the datefield to Now + number of days,minutes,weeks etc in the targeted module.
Eg. Workflow for parent module Project, On all new record creation, I create a Project Task with End date = Now + 9 week. It will create the Project task with end date with 9 weeks from now.
