I hope you can find a solution here.

let preDateTime = new Date("2022-03-31 22:26:00");
let newTime = preDateTime.toLocaleTimeString('en-US');
let hour = newTime.split(":")[0];
let amPm = newTime.split(" ")[1];
let seconds = newTime.split(":")[2].replace(amPm,'');;

let noAmPm = newTime.replace(amPm,'');
let noAmPmSeconds = noAmPm.replace(":"+seconds,'');
let noSeconds = newTime.replace(":"+seconds,' ');

if(parseInt(hour)<9){
    newTime = "0"+newTime;
    noAmPm = "0"+noAmPm
    noSeconds= "0"+noSeconds
    noAmPmSeconds = "0"+noAmPmSeconds;
}

console.log(newTime); //10:26:00 PM
console.log(noAmPm); //10:26:00 
console.log(noSeconds); //10:26 PM
console.log(noAmPmSeconds); //10:26

I have done it! It looks like this:

console.log(new Date().toLocaleTimeString() + " " + new Date().getSeconds() + " seconds");

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

with the moment.js library it works in this way:

var result = moment().format('hh');
alert(result);
<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.17.1/moment.min.js"></script>

var date1 = new Date(1945,10,20, 17,30)
var date2 = new Date(1970,1,8, 12,00)

console.log(date1.getHours() - 8 + (date1.getMinutes()/60))

console.log(date2.getHours() - 8 + (date2.getMinutes()/60))

What about these methods

new Date().getHours()

new Date().getMinutes()

For example:

 var d = new Date();
 var n = d.getHours();

Edited

Return the hour, according to universal time:

new Date().getUTCHours()

Example: 

var d = new Date();
var n = d.getUTCHours();

var datetime = ("2000-01-01 01:00:00 UTC");
var d1 = new Date(datetime);
var minute = d1.getUTCMinutes();
var hour = d1.getUTCHours();
if(minute > 0)  
     alert(hour+"."+minute);
else
     alert(hour);

Use the following code:

var datetime = "2000-01-01 01:00:00 UTC";

var dt = new Date(datetime);
var hr = dt.getUTCHours();
if(hr > 12) {
   hr -= 12;
}
alert(hr);

Assuming you have a Date object like

var datetime = new Date("2000-01-01 01:00:00 UTC"); // might not parse correctly in every engine
// or
var datetime = new Date(Date.UTC(2000, 0, 1, 1, 0, 0));

then use the getUTCHours method:

datetime.getUTCHours(); // 1

As an alternative if you want to get the time from a string - 

var datetime ="2000-01-01 01:00:00 UTC";
var myTime = datetime.substr(11, 2);
alert(myTime) //01
