Timezone

Timezone adds dayjs.tz .tz .tz.guess .tz.setDefault APIs to parse or display between time zones.

var utc = require('dayjs/plugin/utc')
var timezone = require('dayjs/plugin/timezone') // dependent on utc plugin
dayjs.extend(utc)
dayjs.extend(timezone)

dayjs.tz("2014-06-01 12:00", "America/New_York")

dayjs("2014-06-01 12:00").tz("America/New_York")

dayjs.tz.guess()

dayjs.tz.setDefault("America/New_York")
