We have servers with high uptime values. I can see several errors and warnings when I look at the kernel message buffer with
dmesg command. Newer kernels supports printing monolithic time information for every lines in kernel message buffer which starts from 0 when system is power up.
But when the server is up for a long time, it is hard to understand that whether a printk time with a value of 30 million is closed to today or not. So, is there any way to put a custom message into kernel buffer with current monolithic time?
