    Adding to what the previous posters have said, make sure your date is valid. For example, 2011-02-31 is an invalid date, which MySQL will turn into 0000-00-00.

    Illegal DATETIME, DATE, or TIMESTAMP values are converted to the “zero” value of the appropriate type (‘0000-00-00 00:00:00’ or ‘0000-00-00’). (MySQL documentation)
