Your statement is in conflict with the message exchange, referenced by the bug I linked to, with, as I understand it, the authors of the standard:
Not really. In that email exchange one of the authors of the RFC mentioned a goal of the RFC. The part of the RFC that I quoted, though, is an explicit exception to that particular goal. The RFC had several goals, they sometimes conflicted, and the RFC's text was a compromise. I was involved with the drafting of the RFC, and remember the history reasonably well.
The ISO output from date can not be used, as it uses a "," as fractional separator
You can use the following if you want subsecond resolution with both 'T' and '.':
date '+%Y-%m-%dT%H:%M:%S.%N%:z'This won't work for some historical timestamps (e.g., the Netherlands before 1937) but RFC 3339 doesn't support them anyway so it's probably good enough.
