isort . && black . && mypy . && flake8whats-new.rstFollowing up on #4684, this PR makes changes to our encoding / decoding process such that
cftime.datetimeobjects can be roundtripped exactly. In the process, because it made the tests cleaner to define, I added cftime offsets for millisecond and microsecond frequency as well.As I note in the what's new, exact roundtripping requires cftime of at least version 1.4.1, which included improvements to
cftime.num2date(Unidata/cftime#176, Unidata/cftime#188) andcftime.date2num(Unidata/cftime#178, Unidata/cftime#225).
