I'm trying to create a timer from when the user clicks a button. To do this I tried to calculate the difference between two date objects. When I output the difference, it works. However thetoLocaleTimeString call returns a string with an extra hour added:
var start;
var timer;
function myTimer() {
var current = new Date();
var difference = new Date(current - start);
console.log(difference.getTime(), difference.toLocaleTimeString(navigator.language));
document.getElementById("timer").innerHTML = difference;
document.getElementById("timer2").innerHTML = difference.toLocaleTimeString('en-GB');
}
start = new Date();
timer = setInterval(myTimer, 1000);
draw();<h1 id="timer"></h1>
<h1 id="timer2"></h1>What am I doing wrong?
Specify the time zone as UTC in the options argument. Otherwise, the difference date will be adjusted to the user agent's time zone.
document.getElementById("timer2").innerHTML = difference.toLocaleTimeString('en-GB', { timeZone: 'UTC' });
Read more on the options argument and toLocaleTimeString in the MDN documentation.
var start;
var timer;
function myTimer() {
var current = new Date();
var difference = new Date(current - start);
console.log(difference.getTime(), difference.toLocaleTimeString(navigator.language));
document.getElementById("timer").innerHTML = difference;
document.getElementById("timer2").innerHTML = difference.toLocaleTimeString(navigator.language, { timeZone: 'UTC', hour12: false });
}
start = new Date();
timer = setInterval(myTimer, 1000);
draw();<h1 id="timer"></h1>
<h1 id="timer2"></h1>Collected from the Internet
