The time zone is an hour wide. Solar noon and chronological noon cannot coincide with each other throughout an entire time zone.

I would say that Solar noon should occur some time in the noon hour. Solar noon should never occur prior to chronological noon, nor after the noon hour. Solar noon should never occur at 11:00am on the clock. Solar noon should never occur at 11:30am on the clock. Solar noon should never occur at 11:59am on the clock. Nobody should experience solar noon earlier than 12:00pm. Solar noon should be experienced sometime between 12:00pm and 12:59:59pm on the clock. Solar noon should be experienced within the noon hour.

The system that more closely aligns with this is Daylight Savings Time. Standard Time pushes solar noon forward into the morning hours for most people. DST keeps noon in the noon hour for most people. If you want chronological noon to coincide with solar noon, you need to choose DST, not standard time.

Sure, in a properly designed time zone, solar noon will range between a clock time of 11:30 and 12:30 at the edges. But, if you go with permanent DST it will range from 12:30 to 1:30. Nobody in the zone will have solar noon at noon.

No, in a properly designed time zone, solar noon will occur between 12:00 and 12:59:59. Nobody should be experiencing solar noon before chronological noon in a properly designed time zone.

And yet, that is what we have. Boston experienced solar noon at 11:29AM today. New York at 11:40. Los Angeles, 11:37 AM.

Even if we accepted the ridiculous idea

of tolerating solar noon before noon, we would need a fifth time zone (and redrawing of the current time zones) to achieve what you're trying to do. Maine and the rest of New England would have to be moved to Atlantic time instead of Eastern, for example.

If each of us adopted your "noon at noon" standard for ourselves, and we each independently and permanently selected Summer Time or Winter Time in our current time zone, the majority of the US population would be on Summer Time. The majority of the land would be on standard time, but the people are not evenly distributed across that land. The majority of the populace would be on DST.
