Can't use options for time command

[재국 김]

I tried some commands like "time -f "%U" ~~" or "time -o ~~", but
error messages is saying that there is no options like -f and -o which
I found from "man time".

Anyone have same problem here? or am I doing something stupid?

When you just use "time", you are getting a shell builtin. However, the
man page is for the time command (/usr/bin/time). Using the absolute path
to the command will get you to the time command. If you want more
information about the builtin time, then you should check the man page for
your shell, .e.g., bash.
