Hello,

How do you think?
I think test is buggy in "older" operation.
the test is from 9front. I have not tried bell-labs test.

term% man test
          f -older t True if file f is older than (modified before)
                     time t. If t is a integer followed by the letters
                     y(years), M(months), d(days), h(hours),
                     m(minutes), or s(seconds), it represents current
                     time minus the specified time.  If there is no
                     letter, it represents seconds since epoch.  You
                     can also concatenate mixed units.  For example,
                     3d12h means three days and twelve hours ago.
