License Expiration timing

Hi all

So the company I work for does firewall management for some of our customers.

Now our purchasing-guy did not manage to renew a coterm license that expired on September 30th. In the Forti Support Portal the licenses/subscriptions all already say 'expired'. However on the GUI of the Forti it says 'License will expire on 10/3/2022". I assume this is like a 3-day grace period?

Will the license expire at 10/3/2022 23:59:59 or at 10/3/2022 00:00:00?

We use Webfiltering on the affected FortiGates and this will default to block without. So I need to know if I still have time on Monday act (contact Fortinet/Reseller to organize some interim license or turn of webfiltering) or if I need to act on Sunday already.

Thanks so much for your help.
