Prevent parsing to local timezone

Is it possible with dayjs to _not_ parse a date string to the local timezone?

I'm running dayjs on a nodejs server and the server could have to deal with dates in all kinds of timezones. Basically I might get a string get sent to it that looks like `'2021-03-24T10:00:00-04:00'` and when I do anything with that, I want it to retain it's local values and not whatever that would translate to based on the local server.

```
const dateString = '2021-03-24T10:00:00-04:00'
const date = dayjs(dateString)

const time = date.format('h:mm A')
```

If I do the above, what I'd want is for time to be `10:00 AM`, and not `2:00 PM` as I'm getting now (my local server is running in GMT).

Is this possible?

Start by reproducing the behavior with the dayjs(dateString) and date.format('h:mm A') calls shown in the issue. Investigate how parsing an offset date string and formatting it interact, then define and verify behavior that preserves the input's local clock values without depending on the server timezone.
