find the time left in a setTimeout()?

by

Just for the record, there is a way to get the time left in node.js:

var timeout = setTimeout(function() {}, 3600 * 1000);

setInterval(function() {
    console.log('Time left: '+getTimeLeft(timeout)+'s');
}, 2000);

function getTimeLeft(timeout) {
    return Math.ceil((timeout._idleStart + timeout._idleTimeout - Date.now()) / 1000);
}

Prints:

$ node test.js 
Time left: 3599s
Time left: 3597s
Time left: 3595s
Time left: 3593s

This doesn’t seem to work in firefox through, but since node.js is javascript, I thought this remark might be helpful for people looking for the node solution.
