In my system current is now after Jun 30 and so doesn't appear. If the test
passes it's actually a huge problem ;).

Is it necessary to pick dates so close in the "future" when setting up the
test? How about setting such dates to some date when the next version is
likely to be out :). Then at least if it fails it's a convenient time to
ask newbies to upgrade to 7.X or even 8.

It's just a very minor issue, but this has happened before - one release
had the testdate < Y2K.

Cheerio,
Link.
