The SAY2K10 bug

Not to pile on, but you don't want to be overly specific because sometimes people just make mistakes. If someone accidentally gets the month wrong when setting up or configuring their computer, and don't turn on NTP, you could be affecting their ability to send you email and (depending on what the email contains) give you money.

Egregious errors (wrong decade) are one thing, but 26 hours is probably cutting it too close.

I assume the reason it isn't dynamic is to be able to do static string matching / regular expression compilation, rather than recalculate the string to match every time. You could get past that by making it re-compute the date string on restart, assuming you restart frequently enough.
