The bug that he encountered has been fixed.

If the post does not provide enough information, suggest that you try sending a private message to the originator.

For completeness, it is worth nothing that a time event is different from expiring an account.   UTM Local Accounts cannot be configured with an expiration date.   If you want account expiration, you need to use a backend system such as Active Directory which provides that feature.   

However, the time event can be used to limit traffic for specific, for those paths where time filtering is possible.  This includes web filtering and firewall rules.

Basically whats happening here is that, we need to expire a user to RDP to the servers. We are looking for VPN user's login to Sophos SSL Vpn expiration after lets say 2 hours.. not too sure if this is possible tho.

With AD, yes it has the feature but not all the servers are part of ADs..
