I noticed this in the data of some scientists I work with. Another awful thing is that when you tell them they need to format the column as text to prevent this in the future, before the data is put in the column (very important!), they'll eventually try to apply it to their existing fubar spreadsheets as well - in which case the "date-recognized" genes become ... large numbers representing the number of days since 1900, totally unrecognizable.
