"TIME(1)" says it comes with a good many output formating options (or 
conversion strings, if you will), such as (quoting from man(ual) on RH 
Linux - YMMD):
%R  Number of minor, or recoverable, page faults. ...
%F  Number of major page faults the occurred while the process was 
running. ...
and other stuff like that.
That is the kind of stuff I am interested in.
