Hi, You are right, thanks! disabling CONFIG_PRINTK_TIME prevented this timestamps. I believe they should have provide some sysfs entry for this, sorry they did not do so regards, Kevin On Tue, Jun 25, 2013 at 10:05 AM, Mulyadi Santosa <mulyadi.santosa@gmail.com> wrote:

Hi, When I add printk messages, and then try to read /var/log/messages, I see this:
Jun 24 03:43:06 localhost kernel: [ 1858.148661] in my_func1 Jun 24 03:44:03 localhost kernel: [ 1915.150953] in my_func2
What are the numbers is square brackets ? like [ 1858.148661] or [ 1915.150953] ?
IIRC, they are jiffies a.k.a timer clock. It is incremented every 1/HZ second. Major distros usually use HZ=1000 these days.
Looking at kernel config, I believe this parameter is the one that toggle that timestamp: CONFIG_PRINTK_TIME=y
So changing it to N and recompile the kernel should get rid of it.
