I’m not sure what you mean by “jersey finish line indicators” ? Do you mean on the “mini-map” in the upper right-hand corner?
Regarding your Strava times - Zwift Island takes place on Jarvis Island, an actual island in the Pacific ocean. To keep it a real ride and not a trainer ride, it uses those GPS coordinates and, hence, Jarvis’s actual time zone.
Yes, the ‘mini-maps’, both close-up and full course. They used to show where the orange, green, and polka-dot lines were with little indicators. Those are gone now for me.
I get that I’m riding around Jarvis Island, but I’m really in my apartment in Chicago, and I think the time-of-day data should reflect that. So if it’s not a bug, then call it a feature request.
Regarding the time stamp - that’s how Strava is adding it since it’s an actual, real island based on GPS data. We can’t fake that without the entire course being flagged.
