Is it possible to setup a block web rule that allows a site to be viewed at particular times?!

We have a number of social networking sites that we block during normal work hours, but we are keen to allow these to be viewed after 6pm.

Thanks

Yes, perform a WHOIS/Netblock lookup the network/site you wish to block (most sites are have several IP addresses).

http://network-tools.com/
-select Network Lookup
-enter domain name
-click submit

Example
www.myspace.com

Output that you are interested in:
NetRange: 216.178.32.0 - 216.178.47.255
CIDR: 216.178.32.0/20


Now create the rule (please note I am using UTM-1 Edge W/8.0.24x so steps might be different but the functionality exists).

Go to Security/Rules -> click Add Rule (bottom of page)

1: Rule Type
-Block
-Next

2: Service
-Standard Service
-Web Server
or
-Any Service

-next

3: Destination & Source

The connection source is:
-use either predefined object (LAN/WLAN/etc) or enter your own range

And the destination is:
-select specific range
-enter 216.178.32.0 - 216.178.47.255 (using the example above).

-expand Show Advance Settings
-select If current time
-define time

-next

4: Rule Options
-enable Log blocked connections until you are satisfied it works are required then disable after.

5: Done
-enter rule description



Please ensure you Firewall has the correct time and possibly performing a NTP (network time protocol) sync.
