I want to know the answer to the following question:
What kind of clocks did the Romans use?
All the background I'm provided with is that "Although they did not fix their schedules to the clock in the modern sense, ancient civilizations adjusted daily schedules to the sun more flexibly than modern DST does, often dividing daylight into twelve hours regardless of day length, so that each daylight hour was longer during summer.". Is that enough to answer the question?
Answer: no
