If you use this LOAD DATA INFILE, this is not relevant since you need the format correct for that command as its just a raw data load, but very fast.

However, if you want to augment your current process of using the insert statements, then on the MySQL end you can use date manipulation functions to massage the data into a date format on the fly. Please see:

http://dev.mysql.com/doc/mysql/en/Date_and_time_functions.html

and in particular you might use the STR_TO_DATE(str, format) function.
