I am unable to limit the hours squid will accept requests squid3 -v Squid Cache: Version 3.0.STABLE8 <---yes I know its older but will do for my needs. Ive tried this: acl ACLTIME time SMTWHFA 06:00-23:30 http_access allow ACLTIME and ive tried this: acl ACLTIME time 06:00-23:30 http_access allow ACLTIME None of the above actually works. I am trying to shut off squids access between 23:30pm and 06:00am
