See original GitHub issue

Describe the bug UTC diff for same day gives 10800000

let dayjs = require('dayjs')
let utc = require('dayjs/plugin/utc')
dayjs.extend(utc)

console.log('diff', dayjs.utc('2021-06-07').diff('2021-06-07', 'days')) //gives 10800000. Expected: 0 or maybe 1, if timezone difference
console.log('diff', dayjs.utc('2021-06-07').diff(dayjs.utc('2021-06-07'), 'days')) //gives 0, correct

Expected behavior diff = 0 or maybe 1, if timezone difference

How is one supposed to calculate the difference between two timezones? Get the UTC string with format ‘Z’ and then parse int?

EDIT: got it with .utcOffset() / 60
