Convert time xx:xxam or xx:xxpm to ISOString

Question

Is there a know way to convert 10:12am and/or 12:10pm to ISOString format?

So far, I was trying to detect if the the time is an am or pm then remove the last 2 chars. After that im just appending new date string like :

export function timeAMPMToISO(time) {
    var newTime = time.slice(0, -2)
    var isAmPm = time.substr(-2)
    var h = parseInt(newTime.split(':')[0])
    var m = newTime.split(':')[1]
    var date = new Date().toISOString().substring(0, 11);
    if(isAmPm === 'pm'){
        if(h === 12){
            h = h
        }else{
            h += 12
        }
    }
    h = (isAmPm === 'am' && h === 12) ? '00' : h;
    return `${ date }${ h }:${ m }:00.000Z`;
}

I have a feeling that this is not normal.

Is there an existing library for this? MomentJs perhaps? If so, how?

Thanks.

You can parse your input using moment (String, String) and then use toISOString().

Your code can be like the following:

moment('10:12am', 'hh:mma').toISOString()

The hh token matches 1-12 hours, mm matches 0-59 minutes and a matches am/pm
