Parece que hay dos comandos time, uno interno (built-in) del bash y
otro externo (supongo que �ste ser� m�s o menos est�ndar en unix).

La ayuda del primero la puedes consultar con "help time". Por lo que
veo es muy elemental, pero quiz� te sirva:

makoki:~$ time help time
time: time [-p] PIPELINE
    Execute PIPELINE and print a summary of the real time, user CPU time,
    and system CPU time spent executing PIPELINE when it terminates.
    The return status is the return status of PIPELINE.  The `-p' option
    prints the timing summary in a slightly different format.  This uses
    the value of the TIMEFORMAT variable as the output format.

real    0m0.001s
user    0m0.000s
sys     0m0.000s
   

El segundo viene en un paquete independiente en Debian. Tiene su propia
p�gina de manual. Ojo: inv�calo especificando el path del ejecutable:

makoki:~$ /usr/bin/time man time

La descripci�n del paquete para Debian es esta:

makoki:~$ dpkg -s time
Package: time
Status: install ok installed
Priority: standard
Section: utils
Installed-Size: 63
Maintainer: Dirk Eddelbuettel <edd@debian.org>
Version: 1.7-9
Depends: libc6 (>= 2.1.2)
Description: The GNU time command.
 The `time' command runs another program, then displays information
  about the resources used by that program, collected by the system while
  the program was running.  You can select which information is reported
  and the format in which it is shown, or have `time' save the information
  in a file instead of display it on the screen.
  .
  The resources that `time' can report on fall into the general
  categories of time, memory, I/O, and IPC calls.
  .
  The GNU version can format the output in arbitrary ways by using a
  printf-style format string to include various resource measurements.
