Typescript definition for moment-msdate

moment-msdate.ts

import * as moment from 'moment-timezone';

// moment-msdate doesn't provide strong types, so add them here
declare module 'moment' {
    export function fromOADate(oaDate: number, offset?: (string | number)): moment.Moment;
    
    interface Moment {
        toOADate(): number;
    }
}

export * from 'moment-msdate';

embarrassed to say, I finally gave up and did this

        // @ts-ignore
        const nowMS = nowMoment.toOADate(); // this function is bootstrapped onto the moment type by moment-msdate but this lib does not export strong types so we need to tell TS to ignore it.
