Dmesg timestamt format

Hi,

Which format is dmesg's timestamp printed in? I currently have values like 68993.598785 and I can't really figure out how to
transform it into a date/time.

Thanks.
Alejandro.

Hi,

these are seconds since system start.

In Linux systems in general, it is typically the number of seconds
since the device was powered on. It is really not useful for finding
out when something happened; it's basically there to find out how much
time passed between messages. If you want real timestamps, install
syslog.

You may be able to look at /proc/uptime, subtract that many seconds
from current time and approximate the dmesg times based on that.

That is, of course, assuming it started at 0. In the case of N900 I
don't think it necessarily always does. Maybe it depends on the
presence of a charging cable, etc.

Thanks for all three answers. Now I know how to use that value.
