Use a countdown only when a sale really ends

Prepare a small test

Select one discounted product with a documented start and end time. Check timezone, customer segment and what happens when the promotion expires.

Work through the task

The Odoo module page describes a live countdown driven by a pricelist rule. Test the product page before, during and after the sale window, then compare displayed price with checkout.

Check the result

At expiry, refresh the page and confirm the discount and timer both change as expected. Avoid resetting a countdown just to create false urgency.
