           Summary: JS Date object should be more self-dependent
           Product: WebKit
           Version: 412+
          Platform: PC
        OS/Version: Windows XP
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: JavaScript
        AssignedTo: webkit-unassigned at opendarwin.org
        ReportedBy: jhaygood at spsu.edu


It appears that being dependent on OS structures is actually a limitation of the
current date_object limitation. For instance, we can't calculate dates prior to
Jan 1 1970 without crashing on Windows, and even if reimplement that function,
formatting dates can't be done for dates prior to Jan 1 1900, due to limitations.

Perusing the Spidermonkey sources (
http://lxr.mozilla.org/seamonkey/source/js/src/jsdate.c ), I have learned that
they implement everything, and only use operating system libraries to calculate
the following:

- Current Time in Milliseconds
- Time Zone Offset
- Daylight Savings Offset for a given Timezone
- Used for Date.toLocaleString()
- Get a String representing the timezone.
