A time-based policy is an in-school custom policy that is applied to OUs for a specific period of time. As such you can either create a new custom policy or convert an existing in-school policy into a time-based policy.
Time-based policies on DNS and SmartPac behave almost the same as for Chrome Extension, with a few exceptions:
- If a time-based policy comes into effect during a browsing session, the pages will not be re-brokered or refreshed to get the new time-based policy automatically. The user will continue to be filtered as per the previous policy until such time that the user refreshes the page, opens a new tab/page or the 30-minute cookie expires, and the page is brokered again.
- Cookie TTL is valid at the browser level, which means Google opened in a new tab will fetch the cookie TTL from the existing open Google tab.
- If a student is browsing Facebook or Twitter and the time-based policy comes into effect, intermittent policy switching will not happen. The student will continue to get the older policy while browsing Facebook and Twitter.
- Following from the above point, if a student is browsing Facebook or Twitter while a time-based policy is being applied, and that ends and OU policy begins, the student will continue to be filtered as per the time-based policy for Facebook and Twitter.
- Similarly, for YouTube, if a time-based policy begins while the user is browsing YouTube, the time-based policy will not be applied.
- If a video is added to the time-based policy deny list and YouTube is accessed after the start time, then the video will be blocked.
- Keyword scanning will not work if the policy changes (i.e from an OU policy to a time-based policy) in the middle of the session for Youtube even if those are opened in a new tab.
