The branch main has been updated by mhorne: URL: https://cgit.FreeBSD.org/src/commit/?id=96b76a6a1edd6d0e0d4fa07c37d11d5805e8b8b3 commit 96b76a6a1edd6d0e0d4fa07c37d11d5805e8b8b3 Author: Mitchell Horne <mhorne@FreeBSD.org> AuthorDate: 2022-10-12 16:35:23 +0000 Commit: Mitchell Horne <mhorne@FreeBSD.org> CommitDate: 2022-10-12 16:46:12 +0000 swi(9): clean up description of clk_intr_event From what I can tell, setdelayed() was removed so long ago that its mention is more likely to be confusing than helpful. We now have a manpage for hardclock(9), so reference that.
