I want to convert UTC hours to local time using JavaScript it is possible ?
I have last 24 hours in array
let _arrHours = ["4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","1","2","3"]
I read this question Convert Hour UTC to Local using moment.js
It's possible using simple JavaScript ?
I have try to fix it but it's works only India time ? what do for other countries ?
let _arrHours = ["4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "1", "2", "3"];
let _arrDt = [];
for (let t = 0; t < _arrHours.length; t++) {
let tm = _arrHours[t];
tm = parseInt(tm) + 5.5; //indian timezone, I want to do it dynamic country wise !
if (tm > 24) {
tm = tm - 24;
}
else if (tm < 0) {
tm = tm + 24;
}
_arrDt.push(tm);
}
console.log(_arrDt, '_arrDt');
Using new Date().getTimezoneOffset() you can get offset then convert into hour !
Try this code it's help you !
let offset = new Date().getTimezoneOffset(); //get the country wise offset !
if (offset > 0) { //let's convert in to hour
offset = (-Math.abs(offset / 60));
} else {
offset = (Math.abs(offset / 60));
}
let _arrHours = ["4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "1", "2", "3"];
let _arrDt = [];
for (let t = 0; t < _arrHours.length; t++) {
let tm = _arrHours[t];
tm = parseInt(tm) + offset;
if (tm > 24) {
tm = tm - 24;
}
else if (tm < 0) {
tm = tm + 24;
}
_arrDt.push(tm);
}
console.log(_arrDt, '_arrDt');
You can simply use toLocaleTimeString to get local time
let assume you UTC hours is 17
let UTCTime=17:00;
var LocalTime=new Date('2021-09-23T'+ UTCTime+ "z").toLocaleTimeString()
