如何将 dmesg 时间戳转换为自定义日期格式？

Question

I am trying to understand the dmesg timestamp and find it hard to convert that to change it to java date/custom date format.

Sample dmesg log:

[14614.647880] airo(eth1): link lost (missed beacons)

So how do I convert 14614.647880 to a standard date?

dmesg -T may show wrong time, different from date command output.

Workaround is journalctl with -k, --dmesg. I am using -k as it is shorter:

journalctl -k

It will show only kernel messages and correct time.

To show only kernel lines matching phrase:

journalctl -kg phrase
