You could use the 'quota' and 'recent' matches.

I am not sure if squid has options to do time based acl. Traffic shaping does traffic shaping, not time based acls. Anyway traffic shaper should have other means of measuring the time, from an other source, like a netfilter match. Regards, Maciej Soltysiak
