Using Moment.js to convert milliseconds to a duration :
moment.duration(dur)
and then output a string : moment.duration(dur).toISOString()
returns this : PT15336H1S
Obviously 15336 Hours is not a very useful number for a duration.
I have found a workaround to do this which is : moment.duration(moment.duration(d)._data).toISOString()
since duration._data returns a json object of this exact simplified form,
passing it back into the constructor does correctly return the string I want.
example :
var d = 55209601000; //milliseconds
var initialDuration = moment.duration(d)
console.log(initialDuration._data);
//{
// days:30,
// hours:0,
// milliseconds:0,
// minutes:0,
// months:8,
// seconds:1,
// years:1
//}
console.log(initialDuration.toISOString());
// "PT15336H1S"
var newDuration = moment.duration(initialDuration._data);
console.log(newDuration.toISOString());
// "P1Y8M30DT1S"
So obviously this method works, but it feels incredibly hacky. Surely there's a moment.js function or a cleaner way to do this?
