  I am searching the internet for an expression for a text layer to go from 23:50:00 to 23:59:59 (1 second before midnight)

  Al the expression i could find are counting down from 10 min to 0 seconds.

  This should work:

  rate = 1;
  clockStart = (23*60 + 50)*60;
  clockStop = (23*60 + 59)*60 + 59;

  function padZero(n){
  if (n < 10) return “0” + n else return “” + n
  }

  clockTime = Math.min(clockStart + rate*(time – inPoint),clockStop);

  t = Math.floor(clockTime);
  hr = Math.floor(t/3600);
  min = Math.floor((t%3600)/60);
  sec = Math.floor(t%60);
  padZero(hr) + “:” + padZero(min) + “:” + padZero(sec)

  Hello,

  Here’s a solution that will get you from 23:50:00 to 24:09:59 using a text layers source text.

  You can also use the Text >Timecode Effect if you can handle the default font.
  Set your Time Source to custom:
  Time Units = 60
  Starting Frame = 5148000

  fps = (1/thisComp.frameDuration);
spm = 60/fps;
fpm = fps*spm

  s = Math.floor(Math.floor(time)%fpm);
  m = Math.floor(Math.floor(time)/fpm);

  if ((s>9) && (m<10)){
"11"+":"+(50+m)+":"+s
} else if ((s<=9) && (m<10)){
"11"+":"+(50+m)+":0"+s
} else if ((s<=9) && (m>=10)){
"12"+":0"+(m-10)+":0"+s
} else if ((s>9) && (m>=10) && (m<20)){
"12"+":0"+(m-10)+":"+s
}

  Prepare for today and you’ll survive, prepare for tomorrow and you will thrive.
