+`TaskScheduleDefinition` has been updated to also accept an options object containing duration information in the form of days, hours, seconds and so on. This allows for scheduling without importing `luxon`.
+
+```diff
+-import { Duration } from 'luxon';
+// omitted other code
+
+const schedule = env.scheduler.createScheduledTaskRunner({
+-  frequency: Duration.fromObject({ minutes: 10 }),
+-  timeout: Duration.fromObject({ minutes: 15 }),
++  frequency: { minutes: 10 },
++  timeout: { minutes: 15 },
+   // omitted other code
+});

+
+For existing installations the scheduling can be simplified by removing the `luxon` dependency and using the human friendly duration object instead.
+Please note that this only applies if luxon is not used elsewhere in your installation.
