Here's an expression I modified from the book

After Effects Expressions
If you are unfamiliar with expressions, what you want to do is create a new text layer (shift+cntl+alt+T) and twirl open the properties to reveal the source text. Alt+click the Source Text stopwatch and paste this expression:

`var startingHour = 10;`

var startingMinute = 59;

var startingSecond = 4;

var seconds = Math.floor(time) + startingSecond;

var minutes = Math.floor(seconds / 60) + startingMinute;

var hours = Math.floor(minutes/60) +startingHour;

var secondsAsPartsOfAMinute = Math.floor(seconds % 60);

var minutesPerHour=Math.floor(minutes % 60);

function addZeros(rawNumber)

{

if (rawNumber < 10) return "0" + rawNumber;

return "" + rawNumber;

}

addZeros(hours)+ ":" + addZeros(minutesPerHour) + ":" + addZeros(secondsAsPartsOfAMinute);

With this expression you can set your starting time by chaning the "starting" variables. Just in case anything was unclear, here's my work file:
