There is a discrepancy between the function name and the comments around it. Should it be older than one week or one day?

Why do you need to calculate this constant instead of providing a defined value?

Why do you need to calculate this constant instead of providing a defined value?
Review

I guess this avoids any uncertainty about how the number was calculated, or if it was calculated correctly. It's a one time operation right?

Its fine here because we're not updating the relaysToPublish array after this assignment in this function (which would have caused side effects on DEFAULT_LOOK_UP_RELAY_LIST).
Further I'm handling the case where I need to append the array by copying the array in the relay controller.
