Thanks.

I think there should be two recorded startup timestamps instead of one:
the first timestamp recorded as early as possible, and the second - when
Emacs completely finishes loading .emacs and all related files.

The difference between these two timestamps will show how much time the
startup process itself takes.  This is useful for optimization of
.emacs loading.

So a new command emacs-startup-time could display (or non-interactively
return) the duration of the Emacs startup.

A general time difference function would be definitely useful,
but what format it should use?  For the uptime perhaps the standard
format of the `uptime' system command is more preferable, e.g.
"15:16:19 up 51 days 1 year".
