Shouldn't time be gradient? So longer minutes in the summer, and shorter minutes in the winter, so there isn't an hour change?
Sure the planets get pulled closer together, and drawn apart, so shouldn't a clock reflect that?
The UK had different time zones, until the railways were built, and rightly so, as there were different timezones. But technology made that obsolete; but if you have a clock that extends minutes, or decreases them, whereever you are, make a more accurate clock, disregarding this hour forward and back?
And the concept of time; when you are waiting for something, time drags, but when you are excited, time flies. So time is a concept.
