where to change in linux code to convert dmesg uptime to UTC format(human readable)
 

Hi All,

I changed the line CONFIG_PRINTK_TIME=y in kernel-2.6.32-x86_64.config to get dmesg timestamp. I am getting the time stamp in the following:
[ 5.967800] mbr: 0x80 0x00 0x00 0x00 0x01 0x01 0x00 0x83 0x55 0xaa
[ 5.974417] sd 0:2:0:0: [sda] 285155328 512-byte logical blocks: (145 GB/135 GiB)
[ 5.982530] sd 0:2:0:0: [sda] Write Protect is off

I want to convert this uptime demsg to UTC format dmesg (Human readable format). For that where do i need to change in linux code. I dont want any script and all. I need to change in linux code and need to install the image in several servers.

doesn't this do it?

Hi Berhanie,

Where do i need to set this (path)?

this is the command. just type it into a terminal.

Ok.. Thanks for your kind information. But everytime i dont type this command in termainal. The server booting time itself , i need to see the dmesg time stamp in UTC format not in uptime.

The "timestamp" you are seeing in every record is a monotonically increasing timestamp in microseconds (unsigned 64 bit integer) There is no code in the kernel to output it in a date format.

This is partly because during parts of the boot (device initialization) there is no date available yet.

That "time-stamp" is kernel active time since boot. It's a duration, not a date. And it has holes in it, although as pointed out, guaranteed to be increasing. Useful for the kernel (devs), maybe not the rest of us.
