I think the problem is one of presentation and vocabulary, indeed.
I think we should clarify:
- "time string", as returned by format-time-string and accepted
by parse-time-string.
- "decoded time", i.e. a list of the form (SECOND MINUTE HOUR DAY MONTH YEAR IGNORED DST ZONE)
I just pushed a patch which defines the `decoded-time` *type*, so we can
refer to that precise name in docstrings.
- "time counted in seconds" for which we support several representations:
a plain number, a list of integers (HIGH LOW USEC PSEC), a pair of
integers (NUMERATOR . DENOMINATOR).
And part of the confusion for me is that `encode-time` not only encodes
time, but can also be used to convert between different representations
of "time counted in seconds" (in which case it's not the inverse of
decode-time).
