Execute Workflow Rule after Precise Time

Execute Workflow Rule after Precise Time

Hi,

I'd like to execute a Workflow Rule based on a specific sub-status for a Sales Order.

I know how to create it, but I want it to execute precisely 72 hours after it was created.

What would I put in:
Date of Execution
Execution Time
Execution Cycle

and what would I put in:
Time Based Action Execution Time
