Even if I like the idea, I don't think that we need all this machinery to support nanosecond resolution. I should maybe forget my idea of using datetime.datetime or datetime.timedelta, or only only support int, float and decimal.Decimal.
I updated my patch (issue #13882) to only support int, float and decimal.Decimal types. I suppose that it is just enough.
Only adding decimal.Decimal type avoids many questions:
- which API / protocol should be used to support other types
- what is the start of a timestamp?
- etc.
As we seen: using time.time(timestamp=type) API, it will be easy to support new types later (using a new protocol, a registry like Unicode codecs, or anything else).
Let's start with decimal.Decimal and support it correctly (e.g. patch datetime.datetime.fromtimestamp() and os.utime() functions).
