As my kids are counting down to Christmas, I came to wonder how did people measure time through history. More precisely I wonder about unit systems for precision time keeping of years past gone.
I am wondering this, because the other two most prominent units (length and mass), have had many systems of units, which still echo from the past (some louder some less so). So even though I know of fathoms and leagues or slugs and stones, I don't ever remember encountering any other unit system other than that of second, hour, day, month, year.
I've checked Wikipedia at History of timekeeping devices, but only devices are mentioned (see hourglasses, burning incenses etc). However, nothing I could find about the actual names of units.
Has anyone else found the names of the actual units?
UPDATE: Thanks everybody for their responses. All of the answers so far for me had merit, even though on hindsight the question was not strictly engineering - it is more on measuring, which I perceive as a vital part of engineering. I've got to admit that the response is even better that I had hoped. I learned a lot of new things. Hopefully, there will be in time even more informational answers.
