How to Customise new fields for execution time

[PJF]

as mentioned in the user manual I tried to customize fields for Actual execution time and estimated execution time, however I don't see field to add "ID=CF_EXEC_TIME "
I configured field with execution time and its displayed on execution but its not automated as written in manual

as user manual says -
"Testers could specify a duration of test execution. Create custom field with ID =
CF_EXEC_TIME and assign to test cases. Configure it to be displayed and used on execution.
The parameter is counted in minutes.
Create custom field with ID = CF_ESTIMATED_EXEC_TIME to define Expected test execution
time. It should be used in Test Specification and possibly displayed in execution. The
parameter is counted in minutes."

Please let me know how to configure this fields.

You must insert minutes manually, there is no automatic time keeping

It's silly of me to ask this question: But where to insert these lines??
I can find a file "cfields_for_computing_time.sql" in "testlink/third_party/user_contribution" location.

Sorry of being so naive, but I dont know how to "run the query"
I've never worked with the sql before. Can you guide me?
