-- This file contains tests for the event_time_microseconds field for various tables.
-- Note: Only event_time_microseconds for asynchronous_metric_log table is tested via
-- an integration test as those metrics take 60s by default to be updated.
-- Refer: tests/integration/test_asynchronous_metric_log_table.
