Creating a UTC object from a dayjs object fails
Describe the bug Do this:
let plainDate = '2018-02-20T23:59:59.000Z';
let obj = dayjs(plainDate);
console.log(1, dayjs.utc(plainDate).toISOString());
console.log(1, dayjs.utc(obj).toISOString());
console.log(2, dayjs(plainDate).utc().toISOString());
console.log(2, dayjs(obj).utc().toISOString());
The second console.log will print an incorrect date (today at 00:00:00) instead of the original date passed. Doing this however:
console.log(1, dayjs.utc(obj.toDate()).toISOString());
Seems to work just fine.
Expected behavior
Creating UTC Dayjs objects should work the same way as creating regular dayjs objects, which means passing a dayjs object as a parameter should work just fine. Instead, creating a dayjs object from a dayjs object works only if you do dayjs() but not dayjs.utc().
