Zoho API v2 - PHP - InsertLeads - Fields

I want to know, my Leads insertion is successful, but the following fields are not affected.

"Created_By", "Created_Time", "Last_Activity_Time", "Modified_by" and "Modified_Time"

Is it even possible to modify those fields ?

The time fields are filled with the current Date and Time

The "Created_By" and "Modified_By" are filled with the user information of the token giver

For the time type filed, I'm using the following format "2019-05-05T14:20:23+05:30"

For the "Created_By" and "Modified_By", I'm using the desired userid

This is my current code for this,

For the sake of the example, I only show the fields related to the issue. Normally, all other variables are here

$token = "************************";

$module = "Leads";

$Created_By = array("id"=> "35545*************", "name"=>"Steven Smith");

$Modified_By = array("id"=> "35545*************", "name"=>"Steven Smith");

$Last_Activity_Time = "2019-05-05T14:20:23+05:30";

$Modified_Time = "2019-05-05T14:20:23+05:30";

$Created_Time = "2019-05-05T14:20:23+05:30";
