Apart from Thomas' contribution, and the pass-the-buck mentality of many
computing departments (even in Universities, to their shame), if you mount
R on a Unix system (including Linux) then there are no real Y2K issues -
there is a Y2038 issue that will be solved by the 8 byte counter. This is
because Unix/Linux maintains it's system time independently of the
hardware, currently in a 4 byte counter of seconds since 1970. The
hardware clock is only used to compare times at shutdown/startup and by
the clock -w instruction which resets it from system time.

Well one great advantage of R is that you can send them the source code so
they can look for themselves. Try that with other products.

See above re Unix. But presumably they haven't mounted some very well
known packages from Microsoft that are not yet Y2K compliant the last time
I looked at their web site.
Good luck with your quest.
