Sun dials easily give you time to about 2 minutes. You have to apply
the equation of time
but that its often given on the sun dial.
A reasonable long case clock would maintain a minute a week, so you
would need a lot of cloudy weather
to seriously lose track of time.
There was not a need of more accurate time until navigation, railways
and stage coaches with schedules.
Astronomers had to make their own time standards from star or solar
observations.

This evening I happened to hear the nearby church's bell tolling 10
pm, and
thought
that 100+ years ago this could have been the "official" time of the
town,
which
maybe was used by people to set their own clocks (if any). But then I
wondered,
who told the priest what time was it? To what extent the clocks of
two towns
were expected to be close to one another? Does anybody know?
