Personally I think the `uptime' format ("up 3 days,  6:41") is ugly.

I mean something where you can specify a format-string. I have in mind
something like:

(defun format-seconds (format-string seconds)
  "Use FORMAT-STRING to format the number SECONDS.
The valid format specifiers are:
%y is the number of (365-day) years.
%d is the number of days.
%h is the number of hours.
%m is the number of minutes.
%s is the number of seconds.

Upper-case specifiers are followed by the unit-name (e.g. \"years\").
Lower-case specifiers return only the unit."

together with the ability to say eg "%.3y" for 001 years.
