All I am getting is a white rectangle. I am using version 6.35.

By the way I use background color of white.

I changed "consolas" to "Fixedsys" and the "$color(background)" to "$color(notice)" and it shows on mine now.

alias startclock {
  var %color 2.3.5.6.7.10.12
  window -pBw0hf  +d @clock -1 -1 $calc($width($time(h:nn:ss TT),Fixedsys,20,0,1) + 2) 18
  drawrect -nf @clock 0 1 0 0 $calc($width($time(h:nn:ss TT),Fixedsys,20,0,1) + 2) 18
  drawtext -p @clock $gettok(%color,$r(1,7),46) Fixedsys 12 1 1 $time(h:nn:ss TT)
  if (!$toolbar(clock)) { toolbar -au clock "Clock" @clock }
  toolbar -t Clock $day
  .timerclock 0 1 clock.cont
}
alias clock.cont {
  var %color 2.3.5.6.7.10.12
  window -pBw0hf  +d @clock -1 -1 $calc($width($time(h:nn:ss TT),Fixedsys,20,0,1) + 2) 18
  drawrect -nf @clock 0 1 0 0 $calc($width($time(h:nn:ss TT),Fixedsys,20,0,1) + 2) 18  
  drawtext -p @clock $gettok(%color,$r(1,7),46) Fixedsys 12 1 1 $time(h:nn:ss TT)
  toolbar -up clock @clock
}
alias stopclock {
  .timerclock off
  close -@ @clock
  toolbar -d clock
}

The above is my version of it. The time changes colors every second. There is a popup that tells you the day when you hover your mouse over it.
