Why am I not setting the hour and minute of the object?

moment().fromnow() shows time according to system timezone. can it use specific timezone to compare date time e.g i posted something at 2018-11-21 14:00:00, it showing me 1 min ago. but if change the date according to some other timezone it shows like 4 hours ago. can i compare this time against a specific timezone on which time is converted.

Years ago I wrote a similar library for C++, and I wanted to compare the implementations. I am considering rewriting the C++ library to make it align better with the syntax of momentjs.

I have tried to find answers to these questions about moment.js, but have been unable to find anything elsewhere. I'm sorry if this is the wrong place to ask...

What is the minimum supported date-time? What is the maximum supported date-time? What date-time does 0 represent? (What is the Epoch) What is the time resolution (time increment) used internally, milliseconds? Are all dates assumed to be Gregorian calendar? Formally, UTC has leap seconds. does moment support leap seconds (23:23:60), or is it more consistent with unix time? Does is have a way of representing an invalid time, or 'Never' (NAN)? Does it have a way of representing 'Always', or 'from the beginning of time' (-INF)? Does it have a way of representing 'Never', or 'at the end of time' (+INF)?

And again, if this in not the best place to ask this, perhaps you can redirect me to a better place to post these questions.

Thanks for your input.

Using Typescript 3.0.3 and 3.1.3.

When using Moment in other code, we need to be able to pass a moment instance around in a type safe manner.

With the older DefinitelyTyped typings, this worked, but under the included ones in the current release, it doesn't.

``` import moment = require("moment"); import {Moment, utc} from "moment";

public static fromMoment(moment: Moment) {
   // do something with moment in a type safe manner
}

```

The issue in the typings is simply that

interface Moment extends Object {

should read

export interface Moment extends Object {

Hand editing the included moment.d.ts to make this change fixes the problem.

2.10.3

https://momentjs.com/docs/#/parsing/utc/

moment.utc(ts).format(); // 2018-10-25T05:00:00+00:00 moment.utc(ts).toDate(); // Thu Oct 25 2018 07:00:00 GMT+0200

How do I get the toDate format of the date but lose the local timezone (so that the second line displays 05:00:00 GMT+0000). I thought using ".utc" fixed this?
