Just put the script in Alt + R, Then change the second line to the date format you want to be shown next to the Whois.
The script displays the "Whois" in a "@Whois" but i also made the script able to display it into the Status window still, To enable it to send it to the Status window again, Change the "no" where it says: "alias showstatus { return no }" to a "yes".

alias timeformat {
$time
}
alias showstatus { return no }

raw 311:*:{ 
  if ($showstatus == yes) { 
    echo 7=4=7=4= Whois $2 7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=7=4=
