My today reported (and reassigned to linux2.6) bug #517122 doesn't gimme rest. One of the problem of analysis of traces is that some times are recorded since epoch, some are the kernel's "uptime". what puzzles me is:
* Difference between dmesg timestamp and /proc/uptime
$> tcpdump -i bond0 -tt -vvv -n "(dst host raider or src host raider)" -s 192
| head -3; dmesg | tail -1; echo "/proc/uptime"; cat /proc/uptime
...
[250851.259481] device eth1 left promiscuous mode
/proc/uptime
241764.70 224706.33
so I have timestamp in kernel messages bigger than uptime
I wonder why is that? different clock source? any other drift?
or may be 'kernel time' in dmesg is some kind of tick, not time per se?
* Is there an easy way to convert (reliably ;)) timestamp in dmesg to
time since epoch (with mksec precision of cause), so I could easily compare
with output in strace and alike.
Thanks in advance!!!!
