] | No. There is only one global timezone: UTC - unfortunately it's not the default in JS, you have to use the [`…UTC…` methods](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) explicitly to get away from the user's local timezone.
You cannot set a timezone in JavaScript. Start with ... | JavaScript has a built in method to retrieve the timezone offset of the current machine:
```
var d = new Data();
var offset = d.getTimezoneOffset();
```
In the above example, offset would be the minutes offset from UTC to Local Time. If you know your own offset, you can write a global method to take theirs and run a... |
