Time schedule, rules for multiple entries

Dear members,

Trying to establish time restricted access to the internet for specific MAC addresses I use two firewall rules on XG 17.

The first to allow time limited traffic, the second to drop all traffic.

If I use this time schedule:

Friday 11.00 - 12.00 
Weekdays 14.00 - 15.00

for allowing internet traffic, I have no access on Friday 14.00 - 15.00.

Which raises my question: what are the rules for multiple entries. I was not able to find any. Are all entries processed? Or until the first matching day?

Thanks for your time,

Tjaco

BTW: I tried to use Firefox posting this question, but did not succeed, even with popups unblocked. Any suggestions?
