Time of day loadbalance?

 
  when HTTP_REQUEST {  
  set day "Thursday"  
  set starttime "2100"  
  set stoptime "2200"  
  
    Look for the current date of when the irule was processed  
    scan [clock format [clock seconds] -format { %A %H%M}] %s%s curday curtime 
  
    if {($day eq $curday) && ($curtime >= $starttime) && ($curtime <= $stoptime) } {  
             Code here will execute based on the day of time you want to execute this code  
       pool my_Pool member 10.1.2.200 80  
     }  
  }
