Based on the file exerpt you had provided, I performed the file import, and I must say, MySql got it in the right way – the date field was preserved exactly as it was… What import did you use, ODBC or CSV and with what options?
The problem with ODBC is that it tries to figure out the field types and change the values accordingly. Apparently ODBC recognized your “notification date” field – correctly – as date. BTW, you should consider storing that column in a date field because date type corresponds best to that field. In your app you can render the date values as you wish.
Just one more thought: in ODBC text driver you may determine type of the fields. You may want to set “notofication date” to text, but I still suggest you to use date as field type!
