Correct.  What's the problem?

The year value represents the last two digits of a year between 1970
and 2038.  Why not try it?

# date 6811130711

The reason January 2038 works, and November 2038 doesn't, is because
the time stamp wraps some time in 2038.  By then I'm sure we'll have
thought of a fix.
