Date and time in netdocs
Each time the date and time is to be specified, we restate the format, as YYYY... etc. Sometimes we use ISO8601; sometimes we use ISO8601 with the T replaced with a space. I think it's always UTC with no timezone.
- The definitions of these two formats should be centralised, and referenced everywhere
- Any even-more-anomalous time formats should be discovered hopefully as part of that and called out
- The without-T separate date and time format should be deprecated
