Hello     o/

Timed out....

How old - within, say 500 years - are the earliest known human-made time-keeping devices?

[Marty]

Are we counting objects where we believe that they were used in timekeeping ways, but aren't sure? Or are we referring to things that we are certain that they were timekeeping devices?

It had to be back around 5000 B.C.

Historically known to have been used to mark the passing of time for use by humans.

A bit too far back, according to what we have in recorded history....

'Right neighborhood tho!

Well there's the something like Antikythera (not sure on the spelling) mechanism that is not only one of the oldest time pieces but also considered these days to be a computer.

Low tech... MUCH lower tech.


It's the reason we have twelve hour days....

[jim360]

Sundial?

[Marty]

I seem to remember that the twelve-hour thing came from Babylonia...

[BFM_Edison]

The sun. I made it back in the day, so it is indeed manmade and about 4.5 billion years old. Yep.
