Yeah, I shouldn't have been so flippant.  It happened at another company I
worked at, too.  My boss there, who has a Master's in Math, was aghast.

The chance is small, yes; but it has happened to us at my workplace.
In cases where this can be prevented cheaply (one more line of code,
no measurable loss of performance), I take the opportunity to do so.
Granted, it's not always so cheap (such as when the files are poorly
designed and don't even have dates to check!).
