[squid-users] squid acl help needed

Hi,
I am at a loss to configure squid acl meeting the following
requirements.

1. All clients must have internet access throughout the day.
2. Clients 192.168.10.1, 192.168.10.2, 192.168.10.5 (can be
changed to something appropriate if you wish) will have access to all
sites throughout the day.
3. Rest all can access net/other sites throughout but can access yahoo.com and
hotmail.com *only* during 1:00 pm to 2:00 pm

Can this be done with squid? I cannot think of appropriate acls and
appropriate order in which to put them.
Can someone help on this?

With warm regards,
-Payal
