Is that practical? Drift is slow and takes 1 min per century. Let’s say you can live with 10 minutes of drift. That leaves minutes [10-50] which is 4 centuries vs minutes [50-10] where it’s fine which is 2 centuries.
Also, if the problem were time zones, time zones already support non-whole hour shifts, so why not just apply the leap second into all time zones? The reason is that that isn’t what a leap second is. It’s kind of “how much time has elapsed since 1970 midnight” and that number is corrected for with leap seconds. Time zone offsets don’t help you here.
And timezones one hour wide impose about a +/- 30 minute fixed error (and sometimes larger) on top of that - the difference between local mean time and local civil time.
