Createdatetime columns is populating as 0000-00-00 - mysql

Question

I have created one table and inserting values in the table from a csv file using a python code .The createdatetime and updatedatetime columns are set to default CURRENT_TIMESTAMP.But when I am populating the data updatedatetime is populating the correct value but createdatetime is populating as 0000-00-00 00:00:00.
Here is my table definition:
CREATE TABLE `fico_details` (
`adf_contact_id` varchar(100) NOT NULL,
`sf_contact_id` varchar(100) DEFAULT NULL,
`Name` varchar(100) NOT NULL,
`BirthDate` date DEFAULT NULL,
`Address1` varchar(100) DEFAULT NULL,
`City` varchar(100) DEFAULT NULL,
`State` varchar(2) DEFAULT NULL,
`Zipcode` varchar(10) DEFAULT NULL,
`SSN` varchar(10) DEFAULT NULL,
`Address2` varchar(100) DEFAULT NULL,
`City2` varchar(100) DEFAULT NULL,

`Zipcode2` varchar(10) DEFAULT NULL,
`Customerinput` varchar(10) DEFAULT NULL,
`AddrDiscrepancyFlg` varchar(10) DEFAULT NULL,
`Permid` varchar(10) DEFAULT NULL,
`score_date` varchar(10) DEFAULT NULL,
`reason_code_1` varchar(10) DEFAULT NULL,
`reason_code_2` varchar(10) DEFAULT NULL,
`reason_code_3` varchar(10) DEFAULT NULL,
`reason_code_4` varchar(10) DEFAULT NULL,
`CreateDateTime` TIMESTAMP not null DEFAULT CURRENT_TIMESTAMP,
`UpdateDateTime` TIMESTAMP not null DEFAULT CURRENT_TIMESTAMP,
`id` bigint(20) unsigned NOT NULL AUTO_INCREMENT,
PRIMARY KEY (`id`),
KEY `SSN` (`SSN`)
) ENGINE=InnoDB AUTO_INCREMENT=876800 DEFAULT CHARSET=utf8;
please help me to solve it.

I am working on same thing these days.
First of all I use timestamp as the datatype as apart from having datetime capabilities, it has MANY usable functions as a string as well as timestamp datatype.
I got the SAME issue as yours, what I did was alter my table was created, I would click on ALTER table using any Db tool (SQLYog in my case) and then Delete the 0000-00-00 00:00:00 value and uncheck the Not NULL check box.
This issue gets resolved EVERYTIME (whenever I create same type of table/columns)after this simple one step.
Hope this helps you too, let me know if anything still bothers you....!!
