Yes. It talks about the changes we have made on the new ISO. However, your system was not installed from that ISO so that wouldn’t be relevant in this case.
When changes are made on the ISO, except for normal package updates, those updates don’t propagate to existing systems. The date on your system identifies the state it was in when you installed it. This is relevant information. Changing it to a later date doesn’t make sense.
It could be changed to “rolling”, but again, why? Generally, for a change to be performed we would want some kind of benefit.
