Time & Date

I don't think you can selectively have the rule or not, the rule's presence against a virtual server is determined at load time. You can however, use time and date to determine on whether or not your commands fire.

when RULE_INIT {
  set off_hours 0
  set ::time_min [clock scan {10:00}]
  set ::time_max [clock scan {17:00}]
}  
when CLIENT_ACCEPTED {
  set current_day [clock format [clock seconds] -format {%a} ]
  set current_time [clock seconds]
  if {($current_day == {Sat}) or ($current_day == {Sun})} {
    set off_hours 1
  } elseif {($current_time < $::time_min) or ($current_time > $::time_max)} {
    set off_hours 1
  }
}
when HTTP_REQUEST {
  if { !$off_hours} {
    log local0. "Work Hours...processing event commands."
  } else { log local0. "Off Hours...exit event." }
}
when HTTP_RESPONSE {
  if { !$off_hours} {
    log local0. "Work Hours...processing event commands."
  } else { log local0. "Off Hours...exit event." }
} 

When first running this rule, I set the time min to 08:00, and the logs showed:

Dec 12 09:54:19 tmm tmm[9977]: Rule time_based : Work Hours...processing event commands.

Dec 12 09:54:19 tmm tmm[9977]: Rule time_based : Work Hours...processing event commands.

I then updated the time_min to 10:00, and the logs showed:

Dec 12 09:58:41 tmm tmm[9977]: Rule time_based : Off Hours...exit event.

Dec 12 09:58:41 tmm tmm[9977]: Rule time_based : Off Hours...exit event.

This configuration modified from the excellent contribution from Deathbywedgie here:
