Converting to Zone

Change the time zone and update the offset and return a Day.js object instance.

TIP

This requires the Timezone plugin to work

dayjs.extend(utc);
dayjs.extend(timezone);

// this example runs in time zone 'Europe/Berlin' (offset +01:00)
dayjs('2013-11-18T11:55:20'); // '2013-11-18T11:55:20+01:00'
dayjs('2013-11-18T11:55:20').tz('America/Toronto'); // '2013-11-18T05:55:20-05:00'
dayjs('2013-11-18T11:55:20').tz('America/Toronto', true); // '2013-11-18T11:55:20-05:00'

On passing a second parameter as true, only the timezone (and offset) is updated, keeping the local time same.
