covnert european time format to US timeformat withAM/PM-CodePudding

I have a string I am trying to display in EST time with AM / PM additions. Somehow it is not working the way I want it to.

I tried this:

let item = "2022-02-16T20:08:29"

return item.toLocaleString("en-US", {
    timeZone: "EST"
  });

expected output 2/16/2022, 8:08:29 PM

output I am getting 2022-02-16T20:08:29

item is just a string, when you call toLocaleString() on it, the Object#toLocaleString() method gets called, which just returns the toString().

If you first create a Date object from your item, your code works, and the Date#toLocaleString() method is called:

let item = "2022-02-16T20:08:29"

let usDate = (new Date(item)).toLocaleString("en-US", {
  timeZone: "EST"
});

console.log(usDate)

If you just need the time, you can use Date#toLocaleTimeString():

let item = "2022-02-16T20:08:29"

let usDate = (new Date(item)).toLocaleTimeString("en-US", {
  timeZone: "EST"
});

console.log(usDate)

The time you are converting is still a string, to access the method toLocaleString you need to be accessing the Date Object.

The date object accepts a string to parse in the constructor as follows. If you need to convert timezone, then you will need to add in the timezone parameter.

let item = '2022-02-16T20:08:29';

function formatDate(date_string){
  let date = new Date(date_string);
  return date.toLocaleString("en-US");
}

console.log(formatDate(item))
