Hi all
since a recent update ( I think it's related to syslog-ng or systemd) my dmesg logs are filled with kernel timestamps even though I've had them disabled with print.time=N on my kernel line in grub for a very long time.
I've looked though syslog-ng.conf but I can't see anything related to time stamps.
I used a custom kernel and the kernel debug message PRINTK_TIME=n is set so I can't see what's turning on the timing messages. If a userspace tool is doing this, it shouldn't as I've disabled it at the kernel level.
What next to check?
Thanks

Why wouldn't you suspect dmesg? use -t, --notime to get rid of the timestamps.
probably because I've disabled at kernel level the time stamps! why would a userspace tool default to turning them on? cat /var/log/boot shows them as having been logged.
cat /var/log/boot

as do other logs.
I shouldn't have to use a switch that I've never had to use in the past. Time for a bug report.

Welcome to the ever changing world of open source. Linux 3.5 introduced structured logging, which dmesg now reads as of util-linux 2.22. By default, this includes timestamps which most people will find to be hugely beneficial in their logs for the purposes of troubleshooting.

I'm not using any switch with 'dmesg', but /var/log/boot indeed shows timestamps:

BTW, is there a way to localize the timestamps the way I can do with 'date':
$ LC_TIME=C date
Sun Oct 14 15:50:34 CEST 2012
$ date
nie, 14 paź 2012, 15:50:35 CEST
I'd love to find a way to display the timestamps the way that makes sense to me.
