=====================================

------------------
$ time ls
<List of files>

real    0m0.038s
user    0m0.020s
sys     0m0.040s

$ time -v ls
bash: -v: command not found

real    0m0.039s
user    0m0.010s
sys     0m0.040s



$ man times
No manual entry for times

$ info times > dummy
info: No menu item `times' in node `(dir)Top'.

$ times --help
bash: times: --: invalid option
times: usage: times

------------------

Question-1 (time) We can see that user-used-time < sys-used-time?
   Doesn't sys-used-time include user-used-time?
   What is user-used-time?

Question-2 (time) Why does 'time' reject  the '-v' options.
  'info time' contains the followin axample :
   eg$ time -v sleep 4
         Command being timed: "sleep 4"
         User time (seconds): 0.00
         System time (seconds): 0.05
         [snip]

Questin-3 (times) What does the times utility do?


Appendix.

$ which time
/usr/bin/time

$ cygcheck -svr | grep time
mingw-runtime        3.1-1
// Where is the time/times utility
