https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date/toLocaleTimeString

Date.prototype.toLocaleTimeString() Returns a string with a locality sensitive representation of the time portion of this date based on system settings.

var time = datetime.toLocaleTimeString();

Update:

The new locales and options arguments let applications specify the language whose formatting conventions should be used and customize the behavior of the function. In older implementations, which ignore the locales and options arguments, the locale used and the form of the string returned are entirely implementation dependent.

// Depending on timezone, your results will vary
var event = new Date('August 19, 1975 23:15:30 GMT+00:00');

console.log(event.toLocaleTimeString('en-US'));
// expected output: 1:15:30 AM

console.log(event.toLocaleTimeString('it-IT'));
// expected output: 01:15:30
