[Python-Dev] PEP 418: Add monotonic clock

[Victor Stinner]

> Could you (with help from others who contributed) try to compile a table
> showing, for each platform (Windows/Mac/Linux/BSD) which clocks (or
> variations) we are considering, and for each of those:
>
> - a link for the reference documentation
> - what their typical accuracy is (barring jumps)
> - what they do when the "civil" time is made to jump (forward or back)
> by the user
> - how they are affected by small tweaks to the civil time by NTP
> - what they do if the system is suspended and resumed
> - whether they can be shared between processes running on the same machine
> - whether they may fail or be unsupported under some circumstances
>
> I have a feeling that if I saw such a table it would be much easier to decide.
>
> I assume much of this has already been said at one point in this
> thread, but it's impossible to have an overview at the moment.

I don't know where I can get all these information, but I'm completing
the PEP each time that I find a new information. It's difficult to get
the accuracy of a clock and how it handles system suspend.

I'm intereted if anyone has such information.
