In recurrence_sequence_ical, the DTSTART in the recrule is used for all occurrences that follow the first one. This is a design issue because the start time is a mandatory parameter, and its time must be used for every occurrence, by design. For the same reason, the time in the UNTIL field must always be ignored. Problems occur, for example, with the rrule widget in Volto (see also plone/volto#5002), which consistently returns a DTSTART and UNTIL field inside the recrule with a timezone (UTC).

-Require setuptools 68.2 or higher for building the package.
+ignore dtstart and until time in rrule (#23)
 
-When built with setuptools 68.1, you could not import the package, at least not an editable package.
-Note that you can still *install* this package with older setuptools versions.
-See [Plone meta issue 172](https://github.com/plone/meta/issues/172) for details.
-
-New problem though.  `tox -e dependencies` says:
-
-```
-ERROR Missing dependencies:
-	setuptools&gt;=68.2
-```
-
-I tried with `setuptools&lt;68.1', which would also work, but that only changes the message:
-
-```
-ERROR Missing dependencies:
-	setuptools&lt;68.1
-```
-
-I think this is a shortcoming in `z3c.dependencychecker`.  It should not report this as a missing dependency.
-It should see that `pyproject.toml` has this dependency covered.
-
-We definitely should *not* require `setuptools&gt;=68.2` in `install_requires`.
