As you might have guessed by other answers in this thread, this is a
builtin time command from bash instead of the GNU time you find in
/usr/bin ... you can find options of such builtins with bashs help
function:
ogra at styx:~$ help time
time: time [-p] pipeline
Report time consumed by pipeline's execution.
Execute PIPELINE and print a summary of the real time, user CPU
time,
and system CPU time spent executing PIPELINE when it terminates.
Options:
-p print the timing summary in the portable Posix format
The value of the TIMEFORMAT variable is used as the output format.
Exit Status:
The return status is the return status of PIPELINE.
ogra at styx:~$
So you can see the builtin time only knows one option and it will
interpret "--verbose" as the "pipeline" (i.e. the command), which then
causes the error you get ...
