Wrong time output

[hanahaneull]

Describe the bug
Wrong month.
Input

var dayjs = require('dayjs');
let utc = require('dayjs/plugin/utc');
let timezone = require('dayjs/plugin/timezone');

dayjs.extend(utc);
dayjs.extend(timezone);
dayjs.tz.setDefault('Asia/Jakarta');

console.log(dayjs.tz(Date.now()));

Output

d {
  '$L': 'en',
  '$d': 2020-10-20T18:01:44.529Z,
  '$x': { '$localOffset': -420, '$timezone': 'Asia/Jakarta' },
  '$y': 2020,
  '$M': 9,
  '$D': 21,
  '$W': 3,
  '$H': 1,
  '$m': 1,
  '$s': 44,
  '$ms': 529,
  '$offset': 420
}

Expected behavior
The '$M' should be 10 instead of 9
My hard guess is month start from 0. I dont know if this right or wrong. But if right, maybe add feature able to change month start from 1 instead of 0

Information

• Day.js Version: 1.9.3
• OS: Manjaro Linux
• Time zone: GMT +07:00 Asia/Jakarta

First of all, Dayjs use a 0-indexed month.

Please use the appropriate getter to get the result you want, not using the instance's private variable.
