I certainly did. There is a batch process to cull old records. It checks for customers who do not have a date of death recorded but are > 130 years old, as it assumes that we weren't informed of their death.

It takes 130 years from the current date and uses that in an SQL statement to compares it to the date of birth. DB2 doesn't like 1894-02-29.

Apparently it happens every 4 years, but no-one can be bothered to fix it.
