Description
**Describe the bug**
dayjs displays an incorrect time zone offset `+08:41` at January 1, 1888.
JS's native Date object and mement shows the correct offset `+09:00`.
Note that January 1, 1888, is the first day of the current JST Japan Standard Time started.
```js
// No.1 native Date: OK
process.env.TZ = "Asia/Tokyo";
new Date("1888-01-01T00:00:00+09:00").toString().split(/GMT(.\d{4})/)[1];
// => '+0900'
// No.2 moment: OK
const moment = require("moment");
require("moment-timezone");
moment("1888-01-01T00:00:00+09:00").tz("Asia/Tokyo").format("Z");
// => '+09:00'
// No.3 dayjs: NG
const dayjs = require("dayjs");
dayjs.extend(require("dayjs/plugin/utc"));
dayjs.extend(require("dayjs/plugin/timezone"));
dayjs("1888-01-01T00:00:00+09:00").tz("Asia/Tokyo").format("Z");
// => '+08:41'
```
**Expected behavior**
dayjs should displays the correct offset `+09:00` as moment does.
