[Python-Dev] PEP 418: Add monotonic clock (original) (raw)

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.
