I proposed some weeks back, and there was one person that didn't like
the idea, while the others who spoke up were either for it or neutral.
I found myself writing a proper ISO 8601 library starting just after
that (to solve a problem with parsing citations in bibtex, which a user
had reported), and while doing that, I found these accessors to be
really handy, so I added them.
While writing the ISO 8601 parsing library (did you know that
"P1Y2M10DT2H30M/2008W32T153000-01" is a valid duration? ISO 8601
contains multitudes), I also found myself in need of writing functions
to do math on decoded time structures. This all happened on the
scratch/iso8601 branch.
I've now mashed the work there into two commits -- one for the decoded
time stuff, and one for the ISO 8601 work itself.
The new stuff is documented and NEWS'd, but the documentation probably
needs copy-editing. And some concept index entries, perhaps...
