When setting a date, without specifying the time zone, JavaScript will use the browser's time zone. When getting a date, without specifying the time zone, the result is converted to the browser's time zone. In other words: If a date/time is created in GMT (Greenwich Mean Time), the date/time will be converted to CDT (Central US Daylight Time) if a user browses from central US.
