times (clocks) were definitely different per city
Regarding the issue of the absolute necessity of defining a standard time the
book by Peter Galison « Einstein’s Clocks, Poincaré’s Maps » gives some
interesting insight. In particular, since after the mid 19th century trains
were developed while the time was not standardized, many accidents happened
with hundreds of people killed. This led Henri Poincaré, Lorentz and Einstein
(among other mathematcians and physicists) to th enotion of relativity…
Talking time,
https://en.wikipedia.org/wiki/Soviet_calendar
is a good example of a failure to replace thousands of years of reality.
So, maybe some measures (feet etc) will stay with us forever.
(I need to look up how these old cultured talked 'temperature'.)
