Date().getTimezoneOffset()
The getTimezoneOffset() method returns the difference between the time zones of local time and Greenwich Mean Time (GMT).
This difference is returned as an integer.
Although this is a method of a Date object, the actual date and time associated with the date is irrelevant because the time zone difference is based on the environment settings.
