Convert time display to a 24-hour format using JavaScript

Question

Convert time display to a 24-hour format using JavaScript

I managed to convert the time format from GMT to my browser's local time using the following JavaScript code:

var newDate = new Date(timeFromat);
timeFormat = newDate.toLocaleString();

Now, I want to change the time format to a 24-hour clock format like this: 12/16/2011 15:49:37 and I need to accomplish this in JavaScript.

This is what I have tried so far:

var firstPartOftimeFormat = timeFormat.substring(0,9);
var secondPartOftimeFormat = timeFormat.substring(10,20);

However, this method doesn't work properly when the date format is different, such as: 3/16/2011. The following part of the code seems to be effective though.

var time = $("#starttime").val();
var hours = Number(secondPartOftimeFormat.match(/^(\d+)/)[1]);
var minutes = Number(secondPartOftimeFormat.match(/:(\d+)/)[1]);
var AMPM = secondPartOftimeFormat.match(/\s(.*)$/)[1];
if(AMPM == "PM" && hours<12) hours = hours+12;
if(AMPM == "AM" && hours==12) hours = hours-12;
var sHours = hours.toString();
var sMinutes = minutes.toString();
if(hours<10) sHours = "0" + sHours;
if(minutes<10) sMinutes = "0" + sMinutes;
alert(sHours + ":" + sMinutes);

Do you have any alternative suggestions or approaches to achieve this? Your help would be greatly appreciated. Thank you.

try using the

dateObj.toLocaleString([locales[, options]])

method

Method 1 - Utilizing locales

let currentDate = new Date();
console.log(currentDate.toLocaleString('en-CA'));

Method 2 - Applying options

let customOptions = { hour12: false };
console.log(currentDate.toLocaleString('en-US', customOptions));

Utilizing some helpful resources:
Date/toLocaleDateString^_MDN
Date/toLocaleTimeString^_MDN

const lang = navigator.language || navigator.languages[0];
const date = new Date();
const date_locale = date.toLocaleDateString(lang, {
  day: 'numeric',
  month: 'short',
  year: 'numeric'
});
const time_locale = date.toLocaleTimeString(lang);

const formatted = `${date_locale} ${time_locale}`;
console.log(formatted)

We determine the current language by accessing the Navigator object in the Window.
If lang is undefined, default settings will be applied.

To specify a particular format, you can manually set lang to options like: 'en-US', 'eu', 'en-GB', 'de-DE', 'hr-HR', and more.

Here's an instance for changing the time:

const date = new Date();
console.log(date.toLocaleTimeString('en-US')) // 12-hour clock
console.log(date.toLocaleTimeString('en-GB')) // 24-hour clock
console.log(date.toLocaleTimeString())        // Default

Answer №14

This method was successful for me. Instead of de-DE, you can substitute in any language code such as us-GB, nl-NL, and so on.

function displayTime() {
    const currentDate = new Date();
    let currentTime = currentDate.toLocaleTimeString('de-DE', {
        hour12: false,
        hour: '2-digit',
        minute:'2-digit',
        second:'2-digit'
    });
    document.getElementById("MyClockDisplay").innerText = currentTime;
    setTimeout(displayTime, 1000);
}

displayTime();
