BTW, rpm -q --whatprovides /bin/date over here indicates
I've not run the prerequisites for that, but there should be several
specific libraries versions that must be in place. If one or more of
those libraries has been updated from another repositiry or corrupted,
that may be your problem.
Another thought: sometimes folks have a local alias or a similarly named
command in an earlier part of $PATH (e.g. export PATH=$HOME/bin:$PATH)
and then we (they) forget they did that. Or they inherit a system from
another who made a similar modification. "whereis" date should reveal if
that is the case.
