;; Retrieves record IDs from the database based on the timestamp of their last update.

;; The function takes two arguments: dbstruct, which represents the database structure, and since-time, which is a timestamp indicating the time of the last update.
;; The function first defines a few helper functions, including backcons, which takes a list and an item and adds the item to the front of the list. 
;; It then initializes several variables to empty lists: all_tests, all_test_steps, all_test_data, all_run_ids, and all_test_ids.
;; The function then retrieves a list of IDs for runs that have been changed since since-time using the db:get-changed-run-ids function. 
;; It then filters the full list of run IDs to only include those that match the changed run IDs based on their modulo (num-run-dbs).
;; For each changed run ID, the function retrieves a list of test IDs, test step IDs, and test data IDs that have been updated since since-time. 
;; It appends these IDs to the appropriate lists (all_tests, all_test_steps, and all_test_data) using the append and map functions.
;; The function then retrieves a list of run stat IDs that have been updated since since-time.
;; Finally, the function returns a list of associations between record types and their corresponding IDs: runs, tests, test_steps, test_data, and run_stats.
