Hi all, When I use dmesg, I'm often annoyed that there isn't a good way to tell how long ago a specific log line was from. The only accurate way to do so that I've found is to look at /proc/uptime and compare that value to the log line I care about. The ctime and iso options could be useful, but as the manpage points out, they are inaccurate in the case of suspend/resume, and I'd still have to do math in my head to see how long ago something was, even if it's easier to do the conversion than with the default style of timestamp. I'd like to see a value for the --time-format option that prints timestamps as values in seconds relative to the time dmesg was executed. This would allow people to quickly see how long ago a relevant event happened. I'm not sure whether it would make more sense to conceive of times in the past as being negative or positive, but one or the other would need to be selected (one might see both in the case of --follow). Is this a feature people would be open to adding? I'm happy to write a patch if so, but wanted to check here first to see if it's something that'd be likely to be accepted. Thanks, :w
