How can I redirect the output of the “time” command?

Question

I tried to redirect the output of the time command, but I couldn\'t:

$time ls > filename
real    0m0.000s
user    0m0.000s
sys     0m0.000s

If you don't want to mix output from time and the command. With GNU time, you can use -o file like:

/usr/bin/time -o tim grep -e k /tmp 1>out 2>err

while tim is output of time, out and err are stdout and stderr from grep.
