# [2021-06-10] Scheduler

Source: https://developer.nylas.com/docs/new/v2-release-notes/2021-06-10-scheduler/

- The Schedule Editor's opening hours selector now validates that the start time is less than the end time. The validation prevents invalid meeting times.
- Hours are displayed using AM and PM following US locale standards.
- We added `locale12HourTime: true/false`, which allows you to change the clock between 12 hour and 24 hours displays.
