/usr/bin/time does not display max memory usage on Linux

Hello --

The man page for 'time' says that it does not
support all options on all OSs, so some elements
may be reported as 0. I have found this to be
the case, and am wondering if a fix is planned
soon, or if there is another utility I can
use in the meantime. In particular, I'd like
to use the %M option to 'time'. I have found that
it always reports 0, even for simple commands
like 'tar'.

I am using GNU 'time' version 1.7 on Red Hat
Linux 8.0, kernel version 2.4.18-14. Thanks.
