Assuming you are running under Linux (a leap, yes, but probably a pretty
good bet), let me say that I tried this once and although seemingly
simple, it gets ugly after a while. Instead, I ended up parsing
/proc/uptime directly (which is actually not that hard, once you get
over the initial idea).
This is assuming that you actually want to *do* something with the
uptime (I.e., parse it into some kind of actual time representation),
not just display it.
