I've seen a fair bit of confusion about this among the folks who have
some familiarity with it, so lemmie 'splain...
This is a limitation in how Unix implements the clock. Specifically,
it does so as seconds since epoch (midnight, January 1, 1970), and the
data type used to store that number (a 4 byte signed integer). A 4
byte signed integer will overflow at 2147483648. As a result,
2147483648 seconds after the epoch, there will be an overflow, such
that when you make a time() call, you'll get unpredictable results.
In 2039, we'll reach that number of seconds since epoch.
Hope that helps.
