This is to be expected. When you interactively issue the command
"time" from the C shell (which is the default interactive shell),
the shell's internal time function will be used:

% time -h true
-h: Command not found.
0.000u 0.000s 0:00.00 0.0%      0+0k 0+0io 0pf+0w

You need to explicitely specity that you wish to run the actual
time _program_, by prefixing "time" with the path:

% /usr/bin/time -h true
        0.00s real              0.00s user              0.00s sys

This will work; "man 1 time" refers to that program, _not_ to the
C shell's internal implementation.
