Time periods and established connections

What is the expected behavior for an existing connection when the firewall rule that created the connection becomes no longer in its allowed time period?

So my time period is 6am-9pm, and a 100Gbyte download is started at 8:55pm. Should that connection be terminated once 9pm happens, or does XG allow existing connections to continue uninterrupted?

This is what i'm seeing, but i'm concerned that the connection is being allowed by my default rule. Even though my default rule has all applications and web categories blocked, i'm still seeing a small number of connections succeed on the default rule for no obvious reason, eg "settings.data.microsoft.com/" is allowed, while "HK2SCH130021135.wns.windows.com/" is blocked, even though both have the same category and both should be blocked.

I'm also seeing allow's for the rule with the time period on it, even though it's now well and truly outside the time period, so maybe time periods don't work as expected?

Any confirmation on the expected behavior of the time periods and established connections would be appreciated.

Thanks
