Allow users to set their timezone, automatically converting meeting times to their local time. It filters out night-time slots (e.g., 10 PM - 6 AM) from available meeting options, ensuring that users can only book meetings during appropriate hours based on their time zone preferences. Additionally, users can customise their preferred "nighttime" window, providing more control over when meetings can be scheduled. This feature helps ensure users avoid scheduling meetings at inconvenient times and prevents them from missing meetings.
