In a file called "/etc/squid/tws":

 acl time_wastage_sites_ssl  ssl::server_name "/etc/squid/tws"
 acl time_wastage_sites_http dstdomain        "/etc/squid/tws"

 acl privileged_traffic any-of \
    privileged-staff privileged-clients \
    TIMElunch TIMEafterhoursAFT TIMEafterhoursMORN \

 http_access allow privileged_traffic
 http_access deny time_wastage_sites_http

 ssl_bump splice privileged_traffic time_wastage_sites_ssl
 ssl_bump stare all
 ssl_bump bump all

You can probably merge the TIME* ACLs down as well like:
  # lunch
  acl okay_times time ...
  # afterhours PM
  acl okay_times time ...
  # afterhours AM
  acl okay_times time ...
  # Saturday and Sunday all day
  acl okay_times time SA
