Normalize SystemTimeZoneIdentifier offset strings #30

Closed justingrant closed 1 year ago

justingrant commented 1 year ago

SystemTimeZoneIdentifier is under-specified in current 262 with regard to offset time zones. This PR ensures that offset time zone identifiers are always returned in their normal form from this AO.

Note that no implementations currently support offset string time zones so this change will prevent future problems but won't change behavior of any existing implementation.
