Taking more than a quarter of 80-char wide terminal for a timestamp
is a bit too much, IMO. Do we really need 9 characters to print
seconds? It starts from a single digit on boot and it can increase
to 2-3 digits while it's still booting but rarely more than that.
Three digits should be enough for nice looking dmesg.boot. As a
compromise, can we settle with "% 4jd" for the seconds part?
