How can I restrict employees from entering time beyond a certain number of days in the past?

In CORE, you can restrict how far back employees can create or modify time entries using the Close Time Entries setting. Go to Settings > Time & Expenses > Time Entry and enable Prevent modification to past time entries. Then select Older than and enter the number of days (for example, 7 days).

When saved, CORE prevents employees from creating, editing, or deleting time entries older than the specified number of days.
