No worries @djnavarro :) About `week_start` - are you sure we need anything but 1 and 7 (which maps to `week_starts_monday=true/false` respectively)? It's relatively straight forward to implement in c++ (and we should probably do it there) but does anyone ever need that? I'm honestly curious. Maybe someone does need it? About the `change_on_boundary` - would that be useful for rollup too? See [my comment here](https://issues.apache.org/jira/browse/ARROW-11090?focusedCommentId=17503922&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-17503922). [Add/subtract kernels can now handle temporal types](https://arrow.apache.org/docs/dev/cpp/compute.html#arithmetic-functions) so you could use them to subtract a single time unit of duration from a timestamp if that's what you'd need. -- This is an automated message from the Apache Git Service.
