kern.msgbuf_show_timestamp=1

Hi,

In /etc/sysctl.conf I have

kern.msgbuf_show_timestamp=1

and so dmsg has things like

[1353919] swp_pager_getswapspace(32): failed

the [1353919] I guess being the timestamp.

But what is it?

Seconds since boot?

If it's that, then where can the true boot time be 
found?

If not, then what does the number signify?
