Projectionists at cinemas don't get that kind of user privilege, i.e. you get access to the application software on the server (which is frequently embedded within the projector itself). You can ingest films from eternal HDD/SSD, or from internet, and you can also ingest the KDM file containing the decryption key, and you can program shows including ads, PSAs, trailers, and the feature, but you do NOT get access to anything like the date&time, OS or package updates.
It's part of the licencing arrangements with distributors. It's also consistent with the philosophy of only giving a user as much privilege as they need. 99% of time it works as intended, but then you get some clown who forgets to update a certificate. Back-dating a server isn't the solution for an expired certificate in any industry.
