If I recall correctly, it's actually referring to the UNIX date problem, which is a well acknowledged problem in UNIX formatted time which most computers use it will occur in the year 2038. I don't know what the fix is for this, maybe there's a simple solution, but because the issue is still a handful of years away no one's bothered to fix the problem.

Or maybe it's already been fixed. Either way it will cause a problem with timekeeping for computers.

Here is a wiki about it. https://en.m.wikipedia.org/wiki/Year_2038_problem
