Get ISO string from date without time zone

Question

My configuration is the time zone in Lisbon. When I do new Date(), I get the current local date / time, whichFri Apr 28 2017 01:10:55 GMT+0100 (GMT Daylight Time)

When I get the ISO string with toISOString(), it will apply the time zone, and I will get:

2017-04-28T00:10:55.964Z

The problem is that a few minutes ago the date was like this (yesterday):

2017-04-27T23:45:05.654Z

I tried moment.js (new to this) and I did something like this

document.write(moment('2017-04-28').format())

But I get this 2017-04-28T00:00:00+01:00one that is not2017-04-28T00:00:00.000Z

I want to pass this value as a parameter of the restful method for its automatic analysis as a DateTime type, but if I pass the output from the moment.js format, it will be parsed as 2017-04-27 23:00:00.00

moment.js, .

type Components = {
  day: number,
  month: number,
  year: number
}

export default class DateFormatter {
  // 2018-11-11T00:00:00
  static ISOStringWithoutTimeZone = (date: Date): string => {
    const components = DateFormatter.format(DateFormatter.components(date))
    return '${components.year}-${components.month}-${components.day}T00:00:00'
  }

  static format = (components: Components) => {
    return {
      day: '${components.day}'.padStart(2, '0'),
      month: '${components.month}'.padStart(2, '0'),
      year: components.year
    }
  }

  static components = (date: Date): Components => {
    return {
      day: date.getDate(),
      month: date.getMonth() + 1,
      year: date.getFullYear()
    }

Answer 7

, , :

moment().tz("Europe/Lisbon").format('YYYY-MM-DD')

You can see that this works as you think:

moment('2017-04-28T00:00:00+01:00').tz("Europe/Lisbon").format('YYYY-MM-DD') //"2017-04-28"
