Hello FreeBSD folks. A question I've got recently while monitoring a few bugs on my laptop is "Why does dmesg not show timestamps?". My use case is following: once in a while a buggy driver would spill an error into dmesg. It does it periodically, probably in response to some user action. When I look at dmesg I see dozens of similar error messages, but I don't know really how often they happen. Did it happen 15 times in last minute? Or 15 times over this day? Having timestamps would help to correlate errors to other events. I tried searching through old mailing lists and forum and the only thing I found is that someone considered this feature to be a bloat. (NetBSD has it!) Am I missing something obvious? How can I get timestamps in dmesg? It seems to me that this is such an essential feature.. Thanks. Ihor Antonov
