It will take something like 5,000 years for solar time to drift from TAI by more than an hour. Given that time zones change a few times a year in random parts of the world (for example, eastern Kazakhstan changed from UTC+6 to UTC+5 to unify with the rest of the country this year), adding another occasion to change them every few thousand years makes no meaningful difference.
Your example of getting so far off that we have to change _days_ would take several times longer than the distance between the invention of agriculture and now. Honestly, I would be extremely surprised if human civilization survives that long, but even if it does, our descendants can just deal with the problem then. There's no reason to make our lives more difficult _now_ just to deal with this very niche hypothetical scenario.
