What do you mean by "compare"? Are you trying to decide if they represent the same time? Do you want to know which one is earlier? Do you want to know the number of milliseconds between them? As others have said, show your code. – Scott Sauyet Sep 27 '17 at 14:43

String comparison like: `'2017-09-27 16:26:39' < '2017-09-28 06:30:00'` works too in this dateformat. – Roland Starke Sep 27 '17 at 14:43

You could use Date.parse to convert your variables to unix timestamps. Then you could compare the two timestamps like as follows.
var unixtimeOne = Date.parse("2017-09-27 16:26:39");
var unixtimeTwo = Date.parse("2017-09-28 06:30:00");
console.log(unixtimeOne);
console.log(unixtimeTwo);
// You could compare the timestamps as follows
console.log(unixtimeOne < unixtimeTwo)

var date1 = new Date('2017 09-27 16:26:39');
var date2 = new Date('2017-09-28 06:30:00');
var msecs1 = date1.getTime(); // in milliseconds
var msecs2 = date2.getTime(); // in milliseconds
console.log(msecs1 - msecs2); // -50601000

If you are willing to use moment.js, it gives you great comparison methods such as 'isSame', 'isAfter' and 'isBefore':
var x = moment('2017-09-27 16:26:39');
var y = moment('2017-09-28 06:30:00');
x.isSame(y) //false
x.isAfter(y) //false
x.isBefore(y) //true
To find the time difference between the two datetimes:
y.diff(x, 'hours') //14
