Implementing a timed-based trigger create a trigger that is executed if an update is being done on the salary field of the employees table between the hours of 2am and 6am. to test your code, it is ok to either change the system time of your computer or modify the trigger time period (i. e. 2pm to 4pm if you are testing at 3pm). the log activity should be the full system date and time, and the user who performed the update. make sure to test your code by including an example of the trigger executing. null key default | extra |type field employee_id first_name | last_name enail phone_number varchar(20) | yes | thire_date job_id salary commission_pct double manager_id department_id | double |double varchar(20) | yes varchar(25) | no yes uni null null null varchar(25) no | pri | null null null date no varchar(10) no | yes yes yes yes null double null null double null null
