I can write at least a pure Python implementation in the next few days, if not a full C implementation. Shouldn't be too hard since I've got a few different Cython implementations sitting around anyway.

indeed what is the holdup? I don't recall anyone saying it was a bad idea in the last discussion.

Do we just need an implementation?

Is the one in the Bug Report not up to snuff? If not, then what's wrong with it? This is just not that hard a problem to solve.

See my comment from over a year ago: <https://bugs.python.org/issue15873#msg273609>.  The proposed patch did not have a C implementation, but we can use the same approach as with strptime and call Python code from C.  If users will start complaining about performance, we can speed it up in later releases.  Also the new method needs to be documented.  Overall, it does not seem to require more than an hour of work from a motivated developer, but the people who contributed to the issue in the past seem to have lost their interest.
