By default, MySQL 5.6+ has STRICT_TRANS_TABLES enabled in the sql_mode configuration. The DateTime field in MySQL does not support the format used in models.DateTimeField which is basically MySQL format +TIMEZONE OFFSET. 

So in this case, disabling STRICT_TRANS_TABLES should fix the issue, but it didn't.
After another migrate, another error appeared
