I think the latest version can now strptime offsets of the form ±HH:MM with %z, so there's no longer anything blocking you from parsing from all isoformat() outputs with strptime, provided you know which one you need.

I think a from_isoformat() like method that *only* supports isoformat outputs is a fine idea, though, with a fairly obvious interface. I'd be happy to take a crack at it (I've been working on the somewhat harder problem of an iso8601 compliant parser for dateutil, so this is fresh in my mind).

Looks like there is a patch or two and test cases on the bug.


Could anyone put this five year-old bug about parsing iso8601 format date-times
on the front burner?


In the comments there's a lot of hand-wringing about different variations that
bogged it down, but right now I only need it to handle the output of

    >>> dt.isoformat()

Perhaps if we could get that minimum first step in, it could be iterated on and
made more lenient in the future.
