https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=291917 Bug ID: 291917 Summary: [PATCH] dmesg(8): add -T to print timestamps as local datetime Product: Base System Version: 16.0-CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: bin Assignee: bugs@FreeBSD.org Reporter: leah@vuxu.org Created attachment 266503 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=266503&action=edit patch By setting the sysctl kern.msgbuf_show_timestamp, the kernel adds timestamps to each dmesg line. However, there is no convenient way to resolve these into absolute timestamps. Add a flag -T to dmesg to provide this. High precision timestamps (=2) will be printed with microseconds. Adding the functionality to work with -M turned out to be a bit tricky, I had to copy the definition of struct timehands... perhaps this should be moved into a system header?
