Church headquarters has not received a Quarterly Report for the following units:
<several ward names>
This report is now -4 days overdue. Please have them submit as soon as is feasibly possible.
I guess the math works out (the report is due on the 15th, the message was sent on the 11th, and 11 - 15 = -4), but it's certainly unusual to be told that I'm a negative number of days overdue on a due date that is still in the future!
