Time [v 1.7] on my Mandrake system only has one option, and that it -p
 From man (1) time:
=======================================================
OPTION
       -p     When in the POSIX locale, use the precise traditional format
                   "real %f\nuser %f\nsys %f\n"
              (with numbers in seconds) where the number of  decimals  
in  the
              output  for  %f  is unspecified but is sufficient to 
express the
              clock tick accuracy, and at least one.
=======================================================

Just for grins, let's see how my Mandrake machine shows CPU time usage 
for the command date, (with and without -p option):

$ time -p date
