This enables customizing the time of day within which periodic refresh occurs.
Previously docs said it happens between 12am-4am which is misleading, because the code effectively allowed refresh until 4:59:59 AM. The default window is now '0-5', which is practically the same as before.
The comment about checking every 24h hours has been fixed as well. This hasn't been true since commit c4fa76f21792943ea512d24326259f01d2fa7e89
