No Problem whatsoever Geoff, I haven't changed a battery in mine for a
while and one of them thinks we're in 1970 anyway, I suppose it depends how
much of an audit trail you're expected to provide for your data.

I'd recommend that you change your date to 1970 BEFORE you go home in 1999,
the B-D filing interfaces ignore any file/directory (all the way up to the
root directory) modified in the next century, and you need to go out to the
operating system Filer or use ftp to modify them with twentieth century
dates so that you can list files again from within Lysys.
Users might be perturbed if #11 is an empty directory.
