Code:
on 3:text:!save *:#yznb:{
  uptime $time $date $2
  if ($nick == artiiz) {
  msg $chan @ $+ $nick VOD saved at $read(HIGHLIGHT.TXT) }
}

alias uptime_chan return ENTER-HERE-THE-TWITCH-CHANNEL
alias uptime {
  sockclose uptime
  sockopen uptime nightdev.com 80
set %time $1 
set %date $2
set %thing $3
}

ON *:SOCKOPEN:uptime: {
  if ($sockerr) { sockclose $sockname | halt }
  sockwrite -n $sockname GET /hosted/uptime.php?channel= $+ $uptime_chan HTTP/1.1
  sockwrite -n $sockname Host: $sock($sockname).addr
  sockwrite -n $sockname $crlf
}
ON *:SOCKREAD:uptime: {
  if ($sockerr) { sockclose $sockname }
  var %data
  sockread %data
  if ($gettok(%data,1,32) isnum) && ($gettok(%data,2,32)) {
    var %c = $chr(35) $+ $uptime_chan
    if ($me !ison %c) { return }
write -c HIGHLIGHT.TXT
     write HIGHLIGHT.txt %thing $qt(%data) %time %date
  }
}

So.. i lended westor's script http://hawkee.com/snippet/16314/ (Twitch Uptime Informer) and implemented it on your script to make it do what you want.
You just need to change ENTER-HERE-THE-TWITCH-CHANNEL with your twitch channel but without #
I didn't test it but i'm sure it will work cause i changed only the commands on westor's script the rest of the code is the same so it should work just fine.
Credits should go to westor though! smile
