The Date constructor can be passed a time value that is milliseconds since the epoch (1970-01-01T00:00:00Z). The value you have seems to have 4 digits too many, so just divide by 1e4 (or whatever value is appropriate):

var timeValue = 14512768065185892;
document.write(new Date(timeValue/1e4));

There are plenty of questions and answers here on how to format the output as dd/mm/yy (which is a very ambiguous format), e.g.

function formatDMYY(d) {
  function z(n){return (n<10?'0':'') + n}
  return z(d.getDate()) + '/' + z(d.getMonth() + 1) + '/' + z(d.getFullYear()%1e3);
}

document.write(formatDMYY(new Date(14512768065185892/1e4)));
