valueOf function returns the unix timestamp with timezone difference

**Describe the bug**
We are replacing all our components using `momentjs` library with `dayjs` library.
I'm trying to get the unix timestamp of the given date, but I'm getting the timestamp with timezone difference. For example, I've used the example given here https://day.js.org/docs/en/display/unix-timestamp-milliseconds, as mentioned in example

`dayjs('2019-01-25').valueOf()`

**Expected behavior**
As mentioned in the page, it should return the result `1548381600000`. But I'm getting `1548354600000` which is `24, Januaray 2019`.
