Where the period set out in the workflow?

Always work with workflows and just created a first workflow, I want to send a sequence of emails. But when I think the workflow, do not ask me when I want longline action that occurs normally in other applications ask me follows.

__ days
__ hours
__ minutes

For example, if I want to send an email at 5 minutes to modify the field “quote stage”.

I am specifying 5 minutes, and can be one day. So I want to understand where the deadline for the workflow starts running establish.
