Nope. It looks to me [1] that, whilst booting, kernel messages are =
written to that file in one batch after syslogd has been fired up. =
Timestamps of those messages are all showing the very same second.

Linux' dmesg has such a feature [2] I am looking for:

|	-d, --show-delta
|
|		Display the timestamp and the time delta spent between

only the time
|		delta without the timestamp is printed.

Michael

[1] is that correct?
